What alinement specs do you guys think I should run on my 57 F100 with a Crown Vic. I.F.S.

 

I would start by using the alignment specs for the Crown Vic that it came out of.

1999-2005 seem to be:
Caster = 0.5 (+/- 0.75) degrees
Camber = 0 (+/- 0.75) degrees
Toe = -0.25 [toe out] (+/- 0.25) inches

You might want to keep Caster at the positive end of the range. Observe tire wear to determine the final toe specifications. This is a good starting point that should make the truck roadworthy but I'm sure you will have to make adjustments to get where you want (handling and tire wear). Perhaps someone who has done the conversion can advise us what settings they ended up at?

I took mine to a local shop and told em to set it up like a 03 Vic, dont know exactly what there numbers were but they were in spec. Ive been daily driving it for 3 years now with no abnormal tire wear in the front and great handling. now the rears I wouldnt know about because I get a little stupid with my linelock way to often an cant keep tires on more than about a 2 months.
