Title: GS Frame Details
Post by: WkillGS on October 17, 2009, 11:09:48 AM

Here are some pics of the various frame details I've seen on my projects.
First is a 65 front crossmember compared to a 66 frame. Some early 66 cars used the 65 style as well. Note the 65's welded on nose, while the 66 frame has it molded in:


Frame part number and date code stamped on  the drivers side rail by the rear bumper:


VIN stamped on topside of the frame under the drivers door:


VIN stamped on topside of drivers side just above tailpipe hanger. Note the numbers are stamped backwards or upside down or in some sort of a strange combination!:


And another of reinforcements found on the front crossmember of my two Fremont-built 66's. My 65 GS DOES NOT have these!:
 
P.S. FRAME DIMENSION charts are posted in the gallery:http://65gs.com/GS_Gallery2/thumbnails.php?album=22

Looking at a 1966 Buick Parts book, frame pn 9783404 is used on Special & Skylark convertibles, as well as all GS models.
Anyone have a 65 parts book to compare numbers?

I'll take two at that price. Does that include shipping?

Thanks. I guess 'Special' also includes the Skylarks.
The 65 GS was advertised as having a beefier rear crossmember. Maybe that explains the different pn's.
