66 k10 4x4 disc brake/power steering conversion

[66_k10_manny]

I found a brake/booster from a 94 blazer, they didnt have the 97 anymore. I noticed the proportioning valve had the additional lines for the ABS. Am i just going to plug these ports and still be able to use the booster? Also, I'm going to be needing that adapter plate, could you send me the info on ordering one. Im pretty sure I understood you technique on using my stock rag joint, drilling it out and welding it back, so i'll hold off on your flange for now.
