Help ID GM parts please

[Jim Rohn]

As always, thanks in advance:

GM part number 3904750 dial

GM part number 3959360 housing

they appear to be related, the one housing is for the steering column collar and the indicator is for a vehicle with the 3speed automatic, but I have no idea of WHAT years and what vehicles they are for, thanks!

Probably fits quite a few. See if the lens slides into the black housing. The black housing sure looks like the ones in 70-72 chev pickups with the optional TH 350 or TH400 trans.

I was told that a bunch of chevy vans, like early 70s and newer used those as well.

69 and older uses a chrome diecast housing as well as a smaller indicator. and a slightly different shape on the clear lens.

These were all illuminated by fiber optic cable...

Ooops, those won't fit together. There was a bridge shaped black plastic thing that holds the lens.

I have some old GM truck parts books someplace. I'll try to find them tomorrow.

ok, thanks!

#3959360 is listed as a "housing, control indicator (saddle) that applies to '67 thru '69 Series 10 thru 30 Chevy trucks with Turbo-Hydramatic, and '67 to '70 Series 10 thru 30 Chevy trucks with Powerglide. There is a fibre optic conductor that inserts into that housing and feeds down through the steering column to a socket somethere. This illuminates the pointer, which is part of the conductor assembly, which lights up behind the dial.

I am assuming the saddle housing was replaced by black, which needs to be painted to match.

#3904750 is listed as a "dial, indicator (top edge beveled) that applies to '67 thru '70 Series 10 thru 30 Chevy trucks with Turbo-Hydramatic and '71 G-10 thru G-30 (1st design). The 2nd design was bottom edge beveled.

So they do sort of go together.
