right, story goes i was owed 2 diffs from the cossie i bough in October last year , finally got them tonight

one of them is standard but the other one is apprently GRP A, but who constitutes a GRP A diff?

its bigger than a standard one and has a different bolt up system - but apart from that what else?

the chap i got the car from was going to rally it, and he's told me the diff is bomb proof as this is what the diff was going to be for

few pics

maybe JB fletch needs one of these?

 

looks standard to me
post a pic of the rear cover?

 

its not standard as its bigger than a standard diff

 

measure the alloy part where the bolt goes straight through,face to face should be 7/7.5inch?

post a pic up of the rear end and measure the diameter of the drive flanges

 

where has it been stored? in a lake!!

my guess is one is a 7" 4x4 item and the other one a 7.5" from a 2wd car.

its definatley a 7.5 inch 2wd diff, not sure if cosworth tho as the output shafts dont look big enough but i may be wrong

not grpa as they have oil cooler fittings etc or it may have grpa internals who knows?

 

that looks like a a fooked 2wd unit, the case is scrap for defo

 

It will deffo be a limited slip, as if the outside is anything to go by the inside will be welded together with rust!

The greenery growing on it is a nice touch though.

 

in a cold shed! - i'll do some measuring tomorrow and report back

 

it adds to its character!

 

from the lip on the drive flange its a early 2wd diff.and probably siezed inside lol.
