Love it !!

That’s a. Real adventure Jeff 👍👍👍👍👍

My wife ever the good chase car driver shot an action video just to needle me with. She is a Keeper

That was almost an awesome FWD burnout. Shades of RoadKill.

My wife used to do some pretty awesome Burnouts in her 1999 GP GTX! But they smelled different!

Small update, installed the Robert Shaw High Flow 180 degree thermostat, ops and leak check good, may have to install a coolant overflow bottle. Jacked the rear end up, and sprayed the rear lower control arm hardware down with penetrating oil. I am going to see if the 91-95 GM B-body arms actually fit the 71-76 cars also. I have been told they do, and from what measurements I can get to without removing an original they look to be interchangeable. They will let me install the 7/8" rear bar I bought some time ago. I will post some pictures this weekend to see if they actually will work. The bar mounts on these later arms are very different than what I am used to on the stock GM arms of the 70's or 80's.

After work today I did manage to remove the drivers side rear lower control arm to compare it with the set of NOS ones I purchased 5 or 6 years ago. They are the updated design intended for the 1991 and later Chevy Impala SS, and the Police Caprice 9C1. Only used on wagons with the tow package. And surprise they are interchangeable! The hole centers are 1mm longer on the newer Buick parts. I was told they would work on the 71-76 B-Bodies, and the 78 and later B-bodies. I was skeptical, but the GM engineer was correct!. I did get the drivers side installed, and continued soaking the passenger side hardware with penetrating oil.

The newer arms use a different mounting system than I am used to, the older system had bolt in brackets that mounted inside of the C section of the control arms, that had captured nuts to mount the sway bar to. The newer arms use thru bolts & nuts that go thru the sway bar, and use 2 separate plates that go under the C section of the arm. and use spacers on the bolts between the upper surface of the arm, and the lower plate.

I included the GM P/N's for the kit in case it is of use for anyone. The lit Includes 2 Lower control arms with new bushings, all the hardware needed to install the rear bar, and even 4 new control arm mounting bolts and nuts. (that I did not use and my original ones are in good shape. I will post some pictures of the bar installed later this weekend. I do like working on this car, even though it is a 55+ year old rust belt car, with less than 35K original miles on it things still come apart without resorting to heat, BFH's, or saws!

Good info Jeff since I also own a ‘94 Roadmaster. What is the cost and where did you buy them?

Frosty, unfortunately I bought them back in 2016 according to the label. I remember paying about $150 for them from the local Chevy dealership. They were on clearance at the time. actually bought them thinking they would fit the 73 Lemans wagon, but the bushings are for larger bolts.

Then I was going to put them on my fathers 78 Catalina wagon. And they would have worked, but when searching for the longer wagon only rear bar I stumbled on a take off from a road master wagon that included the mounting brackets, so it was easier to just bolt it to the original arms as they had the mounting holes for the brackets.

Then I found them again is the garage and spoke to a retired GM Engineer I know and he said they should bolt on the 71 Catalina, so I tried them and they worked! And as they are actually made for Police package 91-96 Caprice's I think they are perfect for the 71 Police car.

I managed to swap the passenger side lower control arm today, torque all 4 bolts on both arms, and install the 7/8" rear bar, easier than the last rear arms I swapped out. Looked up the 1996 recall on the 9C1 Police cars and Taxi cabs. it seems that the Police cars and Cabs were breaking the lower control arms at the rear bolt holes for the sway bar mounting brackets.

These arms were installed to correct the situation.

The shop that did the Mechanical work just posted a YouTube Video, they did an ok job for Mopar guys.

They only throw me under the bus a little bit.
