front end change

[1tons4life]

I just got my hands on a 67 c30 and i am tring to drop it and get front disc brakes. I that about going with 73 and newer front sup. but is there a easier way like just changing the ball joints to use the 73 spindles or can i bolt on all the 73 and up hardware. how do i lower this thing sorry if this is stupid but i have never done this before.:new

I don't think you can put '73-'87 ball joints in '67 A-Arms. But then again I could be completely wrong. The easiest way would be to either use the donor arms and spindles and then change out the tie-rod ends to the '73 style, or bolt in the entire x-member and the whole shootin-match in one fell swoop!
As far as lowering goes- there are many methods. Some I would recommend and some that would qualify you as bona-fide trailer trash! The first question is "how much drop"?

Best Method: Dynamic Drop with tubular trailing arms or dropped spindles with Shockwave air springs. (i.e. ADJUSTABLE!)

Better Method: Static drop with same arms or spindles w/ stock or lowered springs depending of how much you're lookin for. (i.e. NON-ADJUSTABLE!)

Good Method: Static Drop with lowered springs + blocks, depending on how far you wanna go.

Bad Method- Cut out coils in springs or heat and collapse coils. (i.e. Harsh ride and totally jankity)

the swap to a 73 front is not that hard I did it in a weekend on a gravel floor check the faq section really good info there on this swap make sure to get the entire truck so you have the time to remove EVERYTHING you need (master cyl, ps gearbox etc) i just cut the frame behind front bumper and after motor mount and dropped out engine, trans and suspension all at once

IM going to go with bags just everythings made for the newer c10 or c30 so thats why i what the newer front end theres so many drops you can do with the newer front. does everthing bolt right up or is there so cut and welding need

The 73-87 crossmember swap is basically a bolt in deal. I think there are 2 or 3 holes that need to be drilled, but it isn't bad. I'm quite certain that you can use 73+ ball joints in your control arms and then swap spindles, but the outer tie rod ends are different and you'll need an adapter sleeve. I've only seen the adapters for 71-72 tie rod ends, but they make them for other years. Personally I think you'd be better off either swapping the entire x-member from another truck or just swapping arms. I just swapped the arms, centerlink, tie rods, etc from an '89 burb and everything worked great. Good luck with whatever you decide and
