Mystery part? Anyone know what this is?

[Jory89]

Greetings,

I have a '76 Riviera, 2.0L FI, and was just curious about this weird part that is underneath the bench seat. Haven't seen it in other buses, and can't find any info on it.
Anyone have any ideas? Can post better picture if more details needed.

Thanks!

it is a servo of some kind. Did your bus have any kind of speed control?

My guess is cruise control

I'd say aftermarket cruise also......If there are 4 magnets attached to an inboard C/V joint it would be bingo. I never put one on a bus that I remember, but put a lot of them on Rabbits, Sciroccos, and Dashers. Dealer installed item. Those fuckin car salesmen.
