P/S pump spacers/ bushings

[dpuckett]

Hey, can someone get me a measurement of the length of the little spacers that square up the p/s pump to the vacuum pump on an intercooled truck? The ones that go behind the studs on the engine side of the pump? Some cheesedick decided not to reinstall them somewhere up the line before I got the truck. Dodge has them available for $25 EACH!!! I bought some studs, and am going to cut some steel pipe to the right length. Only problem is, I dont know that length.

I get a measurement of 0.372" so figure 3/8" You may want to look at www.mcmaster.com part number 8491A726 which is a headless fit bushing which is 3/8" id x 1/2" od x 3/8" long. It's a tad bit on the skinny side but a few matched flat washers could fix that. You need to keep the dimensions close otherwise the shaft will become offset in the seal.
