55.2-59 astro van chev 2500 hydroboost mix

[56 3100]

just thought i would pass along my findings on the astro van hydro boost swap info. whereas there isnt to many astro vans to be had in the auto salvages locally . i found a 93 chev 2500 version for $50 on facebook marketplace.upon trying it in place on the CPP frame mount i noticed top cover is real tight fit to floor underneath. after looking at the step mounting surfaces of the 2 master cylinders i was wondering if reservoirs would swap? after rolling the dice on ordering a astro van reservoir on amazon they do indeed interchange! took new rubber seals off new and lubed with brake fluid and pushed in bore of master. then lubed bottom tubes on reservoir and it pushes on chev 2500 mater no problem. adapter plate i made template from original . the difference in height between the 2 reservoirs is 7/16". doesent seem like much but plenty of room to get cover off. cardone # 1R-2058 is for astro reservoir
