thru all the reading I've done on doing a disc brake coversion on my 67 using 71 camaro spindles I will need global west upper a-arms and special lower ball joints assume you use ones from a camaro which needs to be cut .080 anyone ever try milling the lower a-arm on the chevelle .080 bigger. just a thought. :rolleyes:

I dont think its the ball joint case diameter that has to get cut, its the ball joint stud diameter that needs to be machined to fit the camaro spindle. Also people here have used the tall spindes with stock upper A arms using reversed offset upper A arm shafts. I still havent tried a tall spindle conversion, so far the stock spindle conversions have worked ok for me.

It is the outer diameter of the balljoint that gets machined down to fit the a-arm. I would not remove any material from the a-arm to make the balljoint fit as this would cause the arm to crack.

Todds correct,

the outer case of the balljoint gets machined down to fit the A-arms. The arms are already prone to cracking, especially since they are over 30 years old... Not a good idea to machine them...

Droptop is correct in that the stud has to match the spindle, but I don't think its reasonable to machine the stud of a Chevelle ball joint to fit the Camaro spindle... Easier to machine the Camaro balljoint to fit the Chevelle control arm...


FO-FDYFO,

Have you used the Pole Position arms yet? If so, how are they working? I am thinking of getting these in the future...

i have them mounted. they look like they will work great. i am not the first to do this or use these on a chevelle. in the circle track game it is done all the time. i just have to finish putting the car back together i have not alligned it yet because i dont have all the weight sitting on the suspension yet. graemlins/thumbsup.gif

I stand corrected, cant believe I didnt get that after all the posts we have had on the tall spindle conversions. Learn something new everyday smile.gif

If you are going to weld in sleeves, why not use Chrysler screw-in ball joints? Saves the hassle of pressing balljoints forever. Reduces the chance of an old crack in the press fit stamping propagating.
Plus, you can say "It's like a Grand National Car" :D

Screw in sleeves are available from Stock Car Products, Speedway Motors, and probably Summit.
