Looking to swap out my 15" inch wheels for GTA 16" wheels. I am looking at also putting in new delrin bushings so I decided to see how much $$ I can get an A-arm from a junkyard. Looking at car-part.com it shows that there are different a arms for 15" and 16"

I was not aware that A Arms were made differently... What A Arms should I try? I have the stock Delco 10.5 brakes.


I found these choices off of car-part.com

1992 Pontiac Firebird
Control Arm, Front Lower


15" whl Right
15" whl Left
16" whl, perf pkg (opt 1LE) Right
16" whl, perf pkg (opt 1LE) Left
16" whl, w/o perf pkg; tire opt QLC Right
16" whl, w/o perf pkg; tire opt QLC Left
16" whl, w/o perf pkg; tire opt QPE Right
16" whl, w/o perf pkg; tire opt QPE Left

Thanks James!

 

Would the 1LE A Arms be worth the hunt ??

16" whl, perf pkg (opt 1LE) Right
16" whl, perf pkg (opt 1LE) Left
16" whl, w/o perf pkg; tire opt QLC Right
16" whl, w/o perf pkg; tire opt QLC Left
16" whl, w/o perf pkg; tire opt QPE Right
16" whl, w/o perf pkg; tire opt QPE Left

I'm not aware that the 1LE is any different than any other a-arm with a 16-inch wheel. Even the 1LE spindle is simply modified from a regular spindle.

Kind of strange that they delineate 1LE specs on their search engine .... What's up with that?

 

Probably part of the 1LE hype. For example, if you look up parts for the standard J65 rear set-up, 89-92, you'll see something like the following: Rear Left; 1LE Perf Pkg. Amusing because all cars, whether they were 1LE or not, were equipped with PBR's in those years.

I've noted that where car parts are concerned, there's a lot of misinformation floating around the auto parts stores.

^ like how on places like ebay the same part listed for Camaro / Firebird will be $20 more then the same part listed for S10 / S15

 

Got it

 

It was my understanding that all the arms are dimensionally the same, with the exception of the steering stops. These are different to prevent tire to frame/body interference with the different wheel/brake offsets.

 

And you are correct. People shouldn't read too much into how the parts for these cars are listed in current catalogs. Plenty of errors there.

 

I think the link I've posted above covers most everything.

Bushings.

 

I know that the 1LE bushings in the rear control arms have a higher durometer, but I've never seen anything verifiable about that being so elsewhere. Anything you can do, jmd, to point me in the right direction?

Would 25 year old 1LE bushings be superior to new Delrin del a lum bushings?

 

No.
