Looks well dodgy that, I would'nt buy it.

The missing diagonals are the ones that are likly to be in the way while trying to fit the engine and it's mounts. It basicly needs D1+2 , TR5 , engine mounts, seat support bars and all the odd sod brackets for rad ect. It's a shame the seller has decided to sell it as he talked a good build based on 2ltr twin cam.
