Hey Dave , I knew it was just early and late. for most car mfg-er’s you can break down the SN and VIN to glean lots of data about them. There was one image I ran across of the trans ID #’’s brokendown.

I thought maybe the serial number would tell me the exact age of the block. Not critical just curious. Mines definitely the early one, Front distributor, stepped motor mount boss and fitting into late 1973 crossmember with short left mount boss.

I did try the direct link, it doesn’t seem using the preview button lets you see pics in post first either. The frustration with pic’s is both having to preload them into an off-site host (photobucket) vs already saved on my computers HD plus resize to fit 1200 site posting . And then PB wants you to pay to save pics .

MANY site have simple, direct load to the post features . As a real estate broker the Seattle MLS allows me to highlight and upload 50 pics at a time to a listing-no long way round method there . Obviously a better funded site then 1200 but the ideas the same,
Seems there has to be a better way....

And No disrespect for the Admins who run the site , appreciate them and the site being here, thanks!
