Hi,

I purchased a 1969 Buick Skylark GS 400 Stage 1 abut 1 years ago. The car had a pretty serious drivers front collision which required a new front clip. I performed the repairs rebuilt the engine. I am now at point where I would like to restore and want to verify it is a real stage 1. The engine is stamped "RS" and turbo 400 is BB.

What has me concerned is the body plate indicates 44637 while the VIN shows 44437. Can someone advise method to verify all aspects?

Thanks

Mario
