....back to the topic...
I had a full set of BETD metal pivot bearings on a 97 GT LTS-1 frame a couple of years ago and they were fantastic, really smoothed out the ride and didnt squeek unlike the original plastic ones!
Im glad BETD are still in business and getting good praise, I was unaware that I could potentially use their services to come up with engineering solutions that werent already advertised on their website...ill bear them in mind in future.
