Re: [AMC-list] Interesting item in A.M.C....

[Frank Swygert <farna@xxxxxxx>]

The guy who did the work is an experienced hot rodder and has done 
several other swaps and similar rear suspension builds. I'm pretty sure 
he checked parts fit first. I might be mixing ball joints and tierod 
ends as far as taper, I forget now! I do recall quite clearly that the 
taper on the tierods are different between the 70+ small cars and the 
Classic. I had to do some welding and filing to get a pitman arm from a 
79 Spirit PS box to fit the drag link on my Classic properly. I didn't 
have a tight fit all the way through -- welded up both sides of the hole 
and filed to fit. It was fitted MOST of the way through, at least 3/4. 
Welding rod is much stronger than the cast or forged steel, and it 
wasn't a problem. IIRC the newer small cars have the smaller taper (7°, 
I assume) and the big ones had the larger (10° assumed -- that's the 
ball joint ream choices). ------------- Date: Wed, 23 Dec 2009 21:39:35 
-0800 From: tom jennings <tomj@xxxxxxx> I was however talking about 63 
(10,80) CLASSIC, big car, not AMERICAN (01).I'm quite sure that the 
lower ball joint on my 63 CLASSIC has a BIG taper,and the '79 Spirit l 
arm I tried to fit to it the '63 steering knuckle had a SMALL taper.

I might have the parts around to verify this, but I'm pretty sure of this...
I hope the guy in A.M.C. did simply tighten the nut down and hope that would
hold it in. The small taper will of course go into the hole, it just won't
bite into the tapered hole.

Maybe 64-up AMERICANs have large-taper lower ball joints. I know that 79
Spirit has SMALL TAPER lower ball joint. I tried one.
