That is the info I needed to know!
You applied where there is a will there surely must be a way, to get er done. I may have to machine as well although... I might have another way to get er done...
Now that I have a part number at aprox 10,000th larger than required, and my thought now travels & twists into the next dimension...Measure that bushing exactly.
Contact Moog and Spicer since they manufacture them and ask for their assistance in a cross reference list that will give me a range of bushings that will be thinner in diameter that is similar...
Once the bushing is pressed out and obtain interior measurement,I will be able to use the cross reference lists from the manufacturers and possible find one to press in without machining.
Or u may see a photo of me in the back room at Napa opening bushing boxes for a while! (LOL) my bud at Napa said go for it..

What I really would like to accomplish is a save the world (97PA) result where all can simply use a part number that presses right in without machining.
And it all begins because Mark gave me a starting point by posting that part number.
This story will be continued in the future..

sounds like a plan.

Hey, has im now having the same problem. 97 (PA) FLCA Bushings & BJs need to be replaced. no retailers carry them.. and cant find bushings online. but after doing all of my research. Im wondering if they r hard to find because the were made of aluminum & never retailed.
BUT! I took the time and lookd into other buicks made that year(97) & I found that the 97 Regal has its control arms almost with that same Design(1 bushing vertical & 1 horizontal), does any one think they would fit? here'* a link to see List: Search for 'control arm & ball joint assembly' | O'Reilly Auto Parts

Now if only we could find something specific to the 97PA we would want to try them!
I think you will find the Pk Ave'* control arms are much larger than a Regal..It'* a wide ride!

I agree the PA is a wide ride.. But i think that its more so frame wise.. Im gonna run and buy one just to come home and "size match it" if its to big then thts that.. But sumthing has to give rite!? Wat if theres a Caddy wit this type of CA? Ima bout to check

Hey great Shaun! I wish you could find something that does match ..maybe a Deville?
Oh & BTW Welcome to the forum!

I think you should check the specs on this bushing: http://www.oreillyauto.com/site/c/de...2936&ppt=C0318 The '97 Riviera used two different LCAs and one is literally identical to yours from what I can tell. As dumb as the one year only LCA design on your ride is even for GM, I'm thinking they didn't up and manufacture a new item to test just that vehicle. Since they were testing the same suspension set-up on the Riv....... The Riv bushing would be my first choice to check out and the piece is 2.011 Inch O.D if that helps. Also, here is a place that may be of some help to you - Steering & Suspension, All American Cars, Import Cars, Off Road and Trucks | RareParts.com .

While my car is on lift shortly in the am (oil pressure sensor replacement) I will see if I can get an approx measurement of the forward front bushing...and better photo of control arm.

It appears the '97 Aurora might have had that same LCA set-up as yours and the Riviera with the front vertical bushing. I just can't locate the factory specs anywhere of course.... who posts the engineering sheets for such things???? LOL

I have the control arm for a 97-05 regal... I removed mine to do a match n boy is it close! Dang near identical! "As far as positions go" about to try and install it and see
