if the stroke is a f-250 4x4 it has a dana 50 TTB. there pure junk. im not sure if your f1 is 4x4 but they have the similar pos suspension, just the powerstroke has leafs and your has coils. there a tad bit different but there the same design.

 

i have TTB on my f1 i like coils better than leafs

 

i would suggest getting a lift for the front of your truck, maybe a 4in so when you put the PSd in it it will sit close to level. or even a 6in lift if the diesel leaf springs fit in the rear.

 

1,000 to 3,500 sounds about right for a price range for a used psd, but with ur miles and depending on where u live could also factor for the price as well.

 

F150s 4x4 have IFS D44's, aswell with F250s with 5.0L gaz engines

 

so could the f1 suspension hold the PSD
