Suspension swap question.
 

Ok guys got a 69 c10 swb 454 6 lug drum all the way around manual brakes. Got a deal on a 78 c10 that has 5 lug disc front drum rear and it was a big block truck so it has the big block clamshell mounts in it. Can i put the 5 lug suspension from it on my 69 along with brake booster and all?

I know the suspension will swap, I did it on mine. I got a booster, master cyl, proportioning valve combo with the right bracket for our trucks from CPP. I am pretty sure you can upgrade to the clam shell mounts too. Hope this helps, oh and we like pictures!!

Can j still use my manual steering box thats on my 69?

Re: Suspension swap question.
 

The steering box mounts too the frame so there will be no change there.
I'm not sure about the pitman arm from the 69 fitting to the later center link but that should be a easy fix using a later pitman.
If you do the swap I would suggest that you use the whole crossmember. If ya ask me its actually less work than removeing all the parts.
hard brake lines are ran different on the later trucks but will fit these yrs with minor mods.
It's not nessacary to use the later c member though.
One nice thing with the later suspension is most stores will still have the parts on the shelf with out ordering them in. Also usually there is a cheaper price differance with the later parts.
Some say the rubber bushings in the control arms give a nicer ride.

One thing I noticed with my 67 when I had a long water pump on the bbc is the clutch for the fan came really close for comfort too my 4 core rad. But also it was not a gen correct oe fan clutch either. I then used all short water pump stuff and all is great.
You might wanna do a search on the clam shell mounts and exhaust headers/manifolds fitments.

Also idk if you have leaf or coil rear suspension but pretty sure either way the 5 lug rear from the square will need the mounts modded and it will be wider.

Definitely swapping whole crossmember, and i have trailling arm rear. Have the short water pump and maybe someone will chime in on clamshell mounts i am running headers if that matters thanx for your input
