Help, Front end change

[twoskies]

Good Morning
ive got a 1966 c10 short bed, frame was twisted 2 inches
no worries, found another shortbed frame

main question is im going air bags, ive got the A arms from my 1972 c10 was going to cup

ive got access to either a 71 or 72 frame with disc brakes to take the front suspension off , or just about any year squarebody, like to stay with 6 lug, just looks better to me but no worries switching to 5, have a 5 lug rearend off an obs truck to change the rear,
which front suspension will be the easier swap

Thanks for the Help

K.I.S.S. --KEEP IT SIMPLE STUPID!
Parts are readily available for all 3. Why change crossmember when the arms and spindles are 72-87 already. If planning bags are you going rack and pinion? Are you going to section crossmember? Are you Z ing front? In the long run would a aftermarket setup be better?

[twoskies]

no rack and pinion, no zing the front,

just a question if the 1971 or 1972, or the squarebody would bolt up,
i didnt know the crossmember was the same so that would work

i am going with the 72 lower a arms and im guessing most of the 1966 suspension to the others is the same

but Thanks, and nice truck

Control arms both upper and lower are the same from 63 to 72. 73-87 arms have the rubber bushings. To stay 6 lug, use an aftermarket 6 lug rotor that requires a 1.25" spindle

Thank You CWCarpenter

think im going with 66 crossmember and suspension, 1972 A Arms, and drop spindle and conversion kit for 1972

Thank You
