What M/C's will fit Astro hydroboost? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I had my local auto recycling center (junk yard) order me an Astro hydroboost & M/C for my 69. Upon receiving the parts it became obvious that the setup originally came through the firewall at a downward angle which causes the master cylinder reservoir to set at an angle when mounted level in my truck. The hydroboost/MC came from a 1996 GMC Safari. My question is, what master cylinders from other vehicles will bolt up and set properly level for my truck OR what reservoirs can I replace the angled one with? Will an original MC for power disc brakes (71-72) work?
