    is there any advantages to getting a 14bff from a van? i heard they are wider than the ones from the pickups. would the spring perches need to be relocated?

    yeah, spring and shock mounts require relocation if using a Van (P series) 14bff

    if you pull one from a K20 it will bolt right on, if K30 than spring and shocks mounts need to be moved.

    IF you pull one from a C20 (2wd) then the shock mounts may require modification (they hang lower/ cause interference when flexed), but the spring pads are good to go

    so basically, if i get a 14bff from a van, it will be the same width as a d60 front with srw hubs? are the spring mounts and shock mounts the same on a van as on a k5?

    p.s. the pic you submitted answered exactly where i was going with this thread.

    I have a SRW chevy d60. Van width 14ff. The rear perches and everything where not on it when i got it, so it was all replaced. But the 60 and 14 are just about even, or atleast very close. And i have 15x10 rims with 2.5" of backspacing. thats why they stick out that far....

    perch locations:

    1/2 & 3/4 ton trucks = 42.5

    1ton trucks = 40.5

    van axles = wider yet. iirc 49 wide.

    shock mounts:

    1/2 & 3/4 ton trucks = same except 2x4 3/4 ton diffrent.

    1ton trucks = same positions 1 ton only.

    van axles = van position only.
