Looking at getting a 6 lug power disc conversion from GMCpauls as I can keep my ball joints and tie rods. Has anyone used this kit from them? My 67 doesn't come with a brake booster so I'll have to get that as well, how complicated is it to install the booster? I see it goes just right before the master cylinder. Anything else to keep in mind while ordering/installing?

You'll need a Master cyl and proportioning valve for disc brakes also.The install is fairly straightforward but be sure your ball joints and tie rod ends are good or be ready to replace them and the ball joint boots when you do the swap.Might want to anyway since they may be 40+ years old.seeten posted a video on doing a spindle swap a while back.It's a good one to see if you've never done one before,there should be more info in the FAQ's to peruse before you start.research will be your friend since it will help you avoid pitfalls and guide you thru the swap.

I used the GMCPaul kit on my 68. Used the 2" drop spindles as well. Easy to do, but be sure to replace the ball joints/tie rods anyway, as PD said. I didn't do my ball joints and now I get to take the whole thing back apart to do them

As far as the brake booster, I did that too, really easy swap, just be sure you get the pedal rod off of the disc brake truck, the rods between power brakes and manual brakes are different lengths.

Best of luck to you.

Well, that's a big reason why I was thinking of going with GMCpauls set up...as I had recently changed out all of my ball joints and tie rods and steering components. I'm debating on if I want to make it just power brakes, or power disc breaks? I'm trying to keep all of my truck as 100% stock as possible. Plus, the less I do the more money I save towards other parts

Similar kits are also available from CPP, ECE and Performance Online. All of these give you an aftermarket spindle which works with your stock ball joints and tie rod ends. You might want to compare prices before you lay down your money.

True, but only GMC Paul (of the ones listed) are site vendors.

I'm starting to notice that with a lot of these kits if i were to go to a 6 lug front disc set up that uses stock balljoints and tie rods that they won't fit factory 6 lug rims. Is that correct? I really wanna keep my stock rims and hubcaps....or am I reading this wrong?
