I'm confused about what front motor mounts to use on a V8 in my 55 2nd 6100. The ones that are sold by the vendors and listed as V8 arethese 2 1/2" between washers. The 55 shop manual showsthese 1" between washersfor a V8 andthe 2 1/2" between washersfor a 6 cylinder. I have the taller ones in my truck herebut I have a firewall clearance problem with my valve covers. I tried the short mounts and they solve the valve cover problem but they don't line up with the motor brackets(no photo sorry). I'm thinking of modifying the brackets to 1 3/8" between washers. That would solve the valve cover problem and I think they will line up properly . Has anyone ever run into this before? Thanks!
