Have a few old mag features, can't remember the exact dimensions off the top of my head, was running 18" Escort fitment Rondells and mega wide rear tyres from memory. Was just speaking about wheel sizes this morning, plan is to get it painted up then trial fit various offsets and widths of 18" rims and it will be a case of fitting the widest I can throw on basically. Need to find a complete donor Sierra at some point, needs lots of silly bits of trim, wiring and so on.
