Thanks again for your help.
Sorry for not discussing the latest suspension I was considering in my question on clearances. Just thought a generic question would yield more results. Mustang II front suspension may still be my choice, but I measured the car and found that the crown vic suspension might fit. Still deciding which way to go.
1) Does my calculation on the camber gain make sense and would I indeed have to allow over three inches of clearance to accomodate the camber gain and the 1.5" clearance you recommend? This seems excessive because most modern cars have the tires much closer to the inner fender at the top.
2) Is it possible other modern suspensions do not have as much camber gain as the Mustang II?
Thanks
