We have a few in stock if it matches our boosters. Plus if not you can look at an old chevy pickup 1" bore

I had to get a master from a 98+ S10 for it to work with the 7" booster that I got. The 96 master would have fit with some grinding but for me it was just easier to get the newer one that also put the brake lines on the engine side of the master instead of the tire side.
