I think most of those kits are made by Newport Engineering or something similar to that. I believe they are different '54-'55 1st than '47 - '53. Is it possible you have one for the wrong year?

I have a Newport Engineering setup in my '55 1st GMC Suburban. After a little adjustment when I first put it in it has worked great for 7 years now.


1955 1st GMC Suburban | 1954 GMC 250 trailer puller project | 1954 GMC 250 Hydra-Matic | 1954 Chevy 3100 . 1947 Chevy COE | and more...
It's true. I really don't do anything but browse the Internet looking for trouble...
