HI: I am considering changing the rear lower trailing arms. During the summer I had to replace the upper arms as they had disentegrated and popped the metal shell. I used the UMI parts and was satisfied with the quality of the product.... much stronger. Has any one had experience with these from U...

I remove the gauge from the dash and moved the niddle to E and in about a hour it went back to 1/4 tank mark by itself. For years it always bothered me that I coundn't trust it.

Hi Guys I have a 1969 parisienne and need to change the front drums to disc to comply with AU main roads. Anyone know what spindles will fit or if there is a kit off another vehicle that will interchange easily. Thanks Jon

Hi, I just bought a '66 Strato Chief. It's in good shape and driveable but it needs an idler arm for the steeing before I can get the safety done. I've called a few auto supply stores but they don't have Strato Chief listed. Which common model has the same parts? Thanks, Darryl

Has anyone every used a Painless wiring replacement harness? I have some electrical gremlins and would like to just modernize the electrical system while adding a few more circuits for use down the road. Anyone have experience with this kind of job?

I noticed this today with Hawker748 and 67Poncho posting their GM documention. Hawker748's lists F41 Suspension: Firm Ride and Handling, whereas, 67Poncho's lists F40 Heavy Duty Front & Rear Suspension. Can anyone tell me the difference?

I figured I would throw out a feeler as there are some darn knowledgeable guys here. Here is my plan. I would like to update the front suspension to something a little more common for parts and aftermarket support. So the big question is what A-arms could or will swap over? And what spindles could or...

I took my Big Block Pontiac in for a wheel alignment and the mechanic said that the frame had sagged, bent due to the weight of the engine. Is this a common occurence?
