Need to have a look....a friend of mine runs 18" AR Torq Trust on his 63' SWC....
....using offset T-Arms and a VBP Perfomance Plus kit....the size is something like 265/35 ZR18 on the rear wheels with a stock body. Front is 245/45-18
I have seen stock rims (C3 year 81) with 285 tire width using offset t-arms and no other mods.
