Checking Rear Subframe Mounts Are Square

[tom.cilano]

Im thinking of buying a shell thats had new rear subframe mounts is there anything i can check to make sure the subframe will be square and straight??
And also is there anything else i need to check for when buying it?? Other places that rust and so on??

Any help very much appreciated thanks in advance

The factory workshop manual has all the dimensions you need. As for the rest, look for dodgey welds, bog where it shouldn’t be, wrinkles in panels indicating collision damage. Rust could be anywhere so look everywhere for it. Maybe make sure it is what it is not a Fake or worse, stolen.
