Is there any difference in the frame that sits under a Skylark and the frame from a GS? If so what are the difference? Thanks. John
Here is an article I just wrote to help you find your frame numbers: http://www.buickperformance.com/FrameNumbers.htm
George, that 71 frame is built one day after my 71 Stage-1 frame which is8/20/70. They must have had a run on frames then for some reason. Mine is also a HAYES frame. Mine is a late MArch car. Just curious what the Build date on that car is? Is a long way from build time for car but is original. I will have to try the mirror trick to look for VIN. Does it realy work?
I guess they did not rotate their stock very well. I just notice the VIN for that car starts with 14. Mine starts with 16. I would bet car is a February car?
This is all very interesting. Is there anything physically that is different from a Skylark to a GS frame? Thanks, John
the gs frame will have a cross brace at rear from lower control arm bolt hole to upper control arm bolt hole
Thanks George, I feel better about my far off date on my frame now. This just verifies how weird and "off" GM did things sometimes. I also noticed small dent in frame at date marking same as mine. Stamp must have really pushed on frame.
One other question on that car George. Side or top post battery cables? Right about the time they switched I believe.
The frame itself is the same for a Skylark and a GS other than the part numbers. There is no difference in the gauge of the frame and the rear braces are bolt-on. Dennis
