At least your old car is being used for something rather than just crushed as is

Thanks Kat, but it's all gonna start slowing down soon, unbolting and stripping bits off is the easy bit, theres gonna be a lot of cleaning overhauling and painting to be done once all the cutting, welding and fabricating is done.
Then there's the gearbox, that'll be a thread on its own lol, I'll just say this for now, I doubt very much this cars gonna have a clutch pedal, and "wots them buttons for on the steering wheel" ??
Graham,
Cheers mate, a great help.
Thanks all,
Regards Dave

You dont need the horozontal bar between strut tops really, but the escos boys do it a lot when converting to coilover as the escos arches and strut top mounts are not meant to take full load so flex a bit with coilovers. Puma rear inner arch is stronger as its fully load bearing.

Puma back on the lift this morning and I stripped out the old beam axle affair. Next roughly cut off all the no longer needed brackets like fuel tank, charcoal canister, exhaust mounts, pipe clip pins etc. This produced a nice little pile of scrap on the floor.....
This is wot it looks like under the back end now.....
I put the Scorpio rear beam on the transmission jack and shoved it up into place, 3 - 4 inches low cos it clouts the Puma underside here and there.
The reason the back end is such a pig to do nicely is that it hits on the chassis and inner / outer sills so a lot of metal has to be cut away, theres about 3 skins, so this seriously weakens the back of the car, (just for now) lol.
Here's the belly ache remember it still needs to go up about 3" - 4" .....
So a couple of hours carefully un picking layer after layer of sill, inner sill and chassis produced a mess on the floor .....
Won't be opening the Pumas doors lol, until some careful re shaping and re building / welding is done to re - inforce this, both sides now cut out
Another couple of hours saw these fabricated, main inner mounts for the forward rear subframe bushes with captive 12 mm nuts on re inforcing plates, all 2mm thick steel.....
Eventually once they are welded in propery they will have another skin over the top of them, all tied back in to the main rear chassis, which will be reshaped for subframe and suspension / driveshaft clearance. These inner mounts will be welded to the floorpan and once tacked into place a quick geometry check to make sure the wheels end up in the correct place
To make life easier, I bolted these onto the front subframe mounts, lifted it into its final resting place and once I was satisfied it was all sitting exactly in the right place I tack welded them into place, then double checked the wheelbase and centralization.....
This is what it looks like with the back end in place and lined up, with the suspension in the fully extended (full rebound) position, Phat fooker or what ??
So I have now dropped the subframe back out and next job is to weld these inner mounts to the floorpan properly and then painstakingly re build 3 layers of chassis in the new shape needed for the independent rear end.
This will include fabricating some mounts for the stiffener plate which goes over the top of the big subframe bushes and then fabricate the central rear diff mount, and a nice neat "diff bulge" for the boot floor.
Last job today was to sweep out and clean up tons of friggin abrasive black dust that occupied the whole workshop from all the 9" cutting wheels I destroyed earlier LMAO.
All in all I'm happy with a good productive day, and now the rear alignment is correct the rest of the back end installation should go quite smoothly
Chow fr now,
Dave

Could have done a FRP in reverse and cut and removed a peice from each side

Dunno, who's Jacko ??
AFAIK there isn't another one like this
Warren has a nice 4x4 with YB Cossie, and I've only seen one other 4x4 YB one, tho there is 2 or 3 2WD YB Cossie Pumas around.
Thanks guys for the positive comments, keep 'em coming
KAT, didn't want it any narrower lol, by the time them big rear quarter panels go on the wheels will be tucked away nicely
Cheers,
Dave

Yeah Warren, its just a bit wider on the outside edges AFAIK, but it definitely needs a small bulge or I may just put a slighty higher but "flat" boot floor in, will know more when the rear "diff" mount is in.
Looking at yours in the pics, I think the whole beam sits a bit lower than mine, but I wanted mines lowest points (mountings) just higher / level with the main floorpan level, as it was in the Scorpio, to give less chance of snagging on "rough terrain", than if it was sticking down a little
If you know what I mean lol, I think I understand that

Hoping it's gonna be done for the end of November, then I can "shake it down a bit" before the next "Snowman Rally"
Initially in 3.0 Normally Aspirated guise, about 230 hp, 300 ft/lb torque. This is the BOB engine I had in the Scorpio, which is pretty stock apart from a few mods. Will allow me to set the car up without seriously mental power
Over the winter I'll be building a short stroke 2449 cc "screamer version of this engine with lower compression and 2 turbos, will be good for at least 450 bhp and about 500 ft/lb torque. This is because Rally regs will only allow the current engine without turbo(s), but if it comes down under 2500cc then I can run turbo(s).
Dawesy,
Fanks mate, yeah I'm chuffed now it's starting to go together. I started at the back end cos I could see (pardon the pun), this was gonna be the "arse" of the running gear install.
The running gear and steering at the front will go in much easier.
Warren, lol yeah I know what you mean, probably more likely to hit a tree etc
Well not much progress today unfortunately cos work took priority
I managed to get the diff bolted in and get the height / angle of the whole chebang set up correctly ready to make the diff mounting beam tommoz.
I'ts definitely gonna go up into the boot floor by 40mm, so a small box / hump methinks
Will also start reinstating the cut out bits of chassis, layer by layer, and following a nice curve around the forward beam mounts, for suspension arm clearance, giving me ott travel on the arms which can later be contained by the struts and bump stops. At this stage I'd rather have too much travel than not enuf

How does scrutineering work when you build a car from scratch like this, is it a case of having these photos to proove what was done along the way? Or do they just check over the finished article?
I remember being scrutineered but obviously with a stock (ish) car it was over very quick.
