im thinkin about buildin up the f150 into a "tough truck"..why im keeping the ttb i can bounce around and not tear it up i plan on using a 10.25 rear so my speedometer and everything still works. the chevy stuff is just so i can use the same wheel all aruond and just somethin different to work on as everything else i have is 78-79 t see a point to put a straight axle under it anymore. my straight axle trucks feel squishy on the road with deaver springs and the f150 is my work/travel truck sees alot of highway and want to keep it stable.
