I am thinking about going the G-body route as far as upgrading to disc brakes in the front my '66. Mainly for reasons of cost and availability of parts. I can't afford a Good kit and can't find any A-body's or X-body's in the junkyards that will work. Forget about finding the f-body's.. lol

I read in the conversion thread you need to have the ball joints machined to fit the chevelle control arms.. you need G-body upper & lower ball joints & outer tie rod ends..

Another member told me he heated up the arms and pressed the ball joints in to get them to fit.

I was thinking, if I just remove the control arms, ( won't matter b/c the car isnt going on the road anytime soon), and have the holes machined for the G-body ball joints.. Then in the future, when I need to replace ball joints, I can just R&R them normally.. Without machining another set of ball joints, or going at the arms with a torch to get them in..

I figure a typical machine shop would charge $50-$100 to machine all 4 arms. Worth it to me b/c it's cheaper than a kit & I know for a fact I can find a G-body in the junkyard tomorrow and get the parts off it.

Will it work?

As far as rotor size, as mentioned in the conversion thread, I'm not concerned. Stock parts stop G-body's fine and the cars weigh pretty much the same.This car will not be road-raced, or drag raced. Just the occasional weekend cruiser.

My plan is to use good quality rotors, ceramic pads, quality calipers,& braided hoses so I believe it will stop just fine as long as the whole system is in good working order.

Got the G-body spindles with backing plates today.. $38 @ the bone yard. When the time comes, I'll hit the bores in the A-arms with a hone to make the ball joints fit properly and be good to go. :cool:

The A arms are like a a stamped piece of metal. I believe the uppers are bolt in (riveted originally) so unless the bolt holes don't line up, they shouldn't be a problem. The problem with machining the bottoms is there really isn't all that much meat there to begin with. You might be able to get someone to thicken the area by welding, but then you risk stressing the metal. I think it would be better to machine the ball joint and leave the integrity of the A arm.

Hey look on ebay for a kit! I just picked one up for under $350! Spindles and All!
