axle fit question

I didn't find anything relating directly to this in a search.

I have a 1972 Chevy Suburban 3/4 ton and I would like to swap in a 14 FF rear and a Dana 60 front. The donor truck would be a 1991 Chevy 1 ton 4WD SRW. Is this a straight bolt on swap or will there be some fabrication involved?

Thanks!

Re: axle fit question

For the '91 to work it will have to be a R/V series truck, or a Suburban. In '88 when they switched to the new body style, they went IFS up front. The R/V series trucks, K-5's and Suburbans all had SFA up to '91. It should be mostly a straight bolt up. You will need the spring plates off of the donor truck to use on you 'burb as they are larger than a D44. I'm not sure if steering mods are required or not.

Re: axle fit question

Thanks for the info. I did find out the rear end has a different center to center dimension on the spring pad location. I guess '73 and newer are wider than the '72 and older.

Re: axle fit question

Nooooo not ALL 91 3500s were SFA. ONLY the crew cab ones, or very special fleet/utility purchases. Otherwise they (the regular and extended cab ones) were IFS like everything else.

From 88-91 the suburbans and crew cab one tons were redesignated:

R1500 1/2 Ton 2WD Suburban
R2500 3/4 Ton 2WD Suburban
R3500 1 Ton 2WD Crew Cab Pickups

V1500 1/2 Ton 4WD Suburban
V2500 3/4 Ton 4WD Suburban
V3500 1 Ton 4WD Crew Cab Pickups
