C1 Removable Trans Tunnel

[Ted S.]

When did GM quit utilizing "removable tunnel" piece? Also what part numer is shown in the AIM for the piece? Was it 3749911? Thanks Ted

Didn't know they ever had one.

My '58 has the back half of the tunnel, where the shifter is, as a separate piece that is screwed down. I believe it was discontinued sometime in '59. My '58 has one and my understanding is the earlier ones had it. Ted

Ted,
My July 59 does not have one, and I do not beleive that they made it into the 59 model year, but I could be wrong. I have one in storage, and if you need one, drop me an Email.

I've owned 54,55,57,58,59,etc. NONE had removable tunnels.

This is the piece I'm refering to. On my '58 it is screwed in place and my understanding is it was that way on the earlier C1 models. At least in Noland's book he states that this was changed for the '59 model year. I had one '58 owner indicate that his was molded in but later came back and stated it was a separate piece. When we were researching the "Siberian heater holes" the '58 AIM had two other parts removed on the same date in '59 and I believe one of them was the screws holding this piece. Given that I'm wondering if some of the early '59s also had this piece held in place by screws. In the '58 I think you'd have a hard time physically removing it since it goes under the heater/radio console. On my '60 it was part of the floor board.

Ted,
Apparently I was wrong. I looked at some pictures that I had, and I did find an eary 59 that had the removable trans tunnel. I would guess that the deletion of the holes must have happened at the same time as the change to a bonded tunnel.
