I am in the process of installing a Cummins in another truck, and I wanted to go with hydroboost due to space limitations. So I ordered a rebuilt booster and master cylinder. Didn't come with the spacer, pushrod, spring, or retainer. No parts stores or junkyards in this area seem to carry these parts. I know I can get the retainer with a seal rebuild kit, and I could make the spring and pushrod as well as the spacer if I had the dimensions. If anybody has those parts out and can send me pushrod length and number of turns on the spring, as well as wire size and spring length I would appreciate it. Or if you have an extra set you would be willing to sell that would be even better. Kind of stuck at this point.
