Thanks Andy. I will get a 41mm socket and make that my first job
I am really chuffed with the donor, the body is scruffy but the engine and box feel fine - perfect donor really. I was delighted when I found the wheels are 15 inch ones and with brand new tyres. I think they will look great on the car and will clear the rear upright bolts. Sean kindly sent me the document with the mods for the MT75 so I now have a pretty good foundation. Just need to get the garage roof fixed, clear out all the crap and get my building board done, I can then buy the steel in. Can't wait!
