Front subframe info

[franky69c10]

I have a 69 swb and I just bought a 73 front and rear suspention 2 put on my truck so I can have 5lug and disk brakes my question is instead of putting the 73 crossmember on and drilling the other holes so it can make it work can I take everything off the 73 and bolt everything up 2 my 69 crossmember what would b easier

first off these trucks do not have subframes they have crossmembers that the front suspension is attached to

from what i have been told ball joionts and tie rod ends should do it i dont even know for sure if you have to go that far just dont try going from 3/4 to 1/2 and you should be good

my lower controll arms are 75 blazer spindels 72 chevy and they all go to gether fine just so you know

[franky69c10]

Thanks so I can use everything from the 73 and put all of it on my 69 crossmember

[trukindud]

The 73 stuff will bolt up to your front crossmember use the entire drag ( center) link tierod ends as well as the idler arm and pitman arm. It will all bolt on lime they were made for it, the only issue you are going to have is bending some new hard lines for the brakes. Your current lines attach to the brake hoses at the rear of the crossmember while the disc front end will attach the brake hoses to the hard lines in front of the x member. You will have to make some hybrid hard lines for it to work. You will also need the mastercylinder and proportioning valve from the 73 for the disc brakes to function properly. On the rear if your truck is leaf springs, the rear end should simply bolt in place, if your truck has coils, you will have to get a kit, or fab it up yourself, to change the 73 rear end mounting points to bolt up to the trailing arms.

Oh yeah, use the upper and lower a arms from the 73 too, the ball joints are different and the a arms will bolt in place of your current ones.

If you will get the master cylinder and all of the lines and prop valve from the 73, it will all bolt in without making any lines.

Then, unbolt the upper and lower arms from the 73 and bolt them to your earlier crossmember. Change the entire steering linkage from side to side and you're done.
