I have a 55 F100 302 aluminum heads full steel front sheetmetal that has a Fatman Mustang 2 front end on it with stamped arms that has way too short of springs on it. The lower arms are far from parallel to the ground,I've decided to go coilover instead of air & don't mind spending a little extra for a wicked setup. I live in the mountains & making it a protouring style truck as its been chopped,flattened,fat rear fenders,ton''s of work before I bought it. Looking for what everyone has the best luck running tubular arms,coilovers,big brakes on the Mustang 2. It's brutal hitting bumps in the road & completely bottomed out the front going 75 is not pleasant,so it's getting parked & time to redo it.Then it's 4 link & time for the 3 spd to go,then body/paint & time to really enjoy it & start on the 46 F1,also looking at 49 F1 panel & another 55 that will be stock restored rides,we have the bug bad lol.
