LMC carries rebuilt vacuum boosters for a reasonable amount of dough. You'll want the smallest one. I had a 61 C30 and there was one installed under the drivers side seat area-on the frame. When I get around to it, I'll put on on my 61 K10. You'll want to read up on the connections in your Service Manual. The smaller trucks generally didn't have them.
My C30 stopped on the proverbial dime. And yes, it gave 9 cents in change!:)
OK, change that. After looking online to add a link to this for you, I can't find them in their latest online catalog. You may have to call them to find out why. (Their supplier/re manufacturer probably went out of biz.)
