[BuickPower]

Hello, I'm new here and was wondering if anyone here has any idea of the last serial # J4000 that came off the assembly line still under the Kaiser name because i have a 71 J4000 that was made in Dec of 1970 so maybe it is close??? Thanks in Advance!

Mine was built Jan 70. The underhood tag says "Jeep" by Willys, but not Kaiser, same with door post sticker.

They kept using that built by willys tag all the way through 71 at least, even though 63 (iirc) was the last year for the Kaiser-Willys name.
