I have decided to go a different route and I am selling my “73” set up. There are two 037 ECU’s and three 037 MPS’s. A new 017 CHT and a new 012 CHT, plus extra parts. Will not separate. $1,000 plus shipping.

Forgot the throttle body

I'm willing to buy this and split it up for people that need specific pieces.

Can an Admin move this to Parts FS - it'll help the seller reach folks looking for EFI parts.

This is Cars & Rollers.

Hit me for the throttle body if that happens.

What years had the integral return spring?

Will do, haven't heard from the seller yet.

AFAIK 75-76, there was an associated change to the plenum adding extra strength to the return spring mount and a second return spring there as well. The plenum changes also included some plumbing differences so its not a direct swap to earlier cars without changing your air filter housing, oil filler tower/pcv arrangement and hoses.

Plenum in the picture appears to be 75-76 style as well though the air filter appears to be early.

I have ran the late TB on the early plenum with no issues noticed yet.
