Harry - sorry for your loss. That Jag sounds pretty interesting. As far as the wheels go, if the car is roadworthy, take it to a tire/wheel shop and have them fit you up. If it's not and you have a wheel that currently fits the vehicle, take it to a tire/wheel shop, and tell them exactly what car the wheels are going on. The car may not accept stock jag wheels. (Since it has a Chevy stroker in it, it may have a different rear end, axles and hubs) Good luck
