Looking for info on NOS Bendix Hydrovac - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**61ChevyPanel** · 01-08-2020, 03:13 AM

Can anyone identify this unit? I believe I won this in a raffle from Golden State Pickup Parts at a Magic Mountain truck show in 1983. It's been in my closet since then. I don't think the speedo cable goes with it but I had it in the same box. The only number I found was on that little brass tag and nothing came up on an online search. I don't have a use for it.

I have a lot of info at home. I'll have to check tonight. I believe it is a unit that mounted underhood on the fenderwell of light duty trucks. GMC's I think.

Looks like a 63-66 c60 setup that would have mounted on the frame.

measure the diameter of the booster body and if its 7" let me know, but from what I see that is the bigger one for 4000 series up larger size trucks

measure the width of the booster body (what the J hooks are holding together) and the diameter - it sure looks small in these pictures. If it turns out to the the smaller booster like it looks I want it
