LM1s are not COPOs, it was an RPO. Not rare, 10,406 built in the 4 months of availability. It was odd in that it required an optional transmission; the MC1 HD 3-speed was the cheapest at $79 and was dropped as an option at the same time.

I was aware that both are RPO's, I was wondering where they fit in the production numbers you gave. Ie, the L89's bundled with the L78, along with the COPO's if I understand you correctly.

The LM1' were bundled where? In the L65 (350),L48 (ss) or L30 (327)?

Just trying to follow the thought process.

Thanks,
