I have a 57 that I converted to front disk brakes. The car was already running 15in American Racing Wheels. I have the stock 14in spare in the trunk that won't clear the front brakes. If I have a front flat I will have to change out with the rear and put the spare on the rear.

? will a 15in spare fit in the spare well and allow for the trunk lid to close?

? if I change out the spare to the rear -- the wheels will be mis-matched and will it injure the posi rear to get home?

Thanks
