Bone yard Hydra boost??
 

Has anyone looked in to adapting the one that started comming on the 05 or 06 GM full size SUV and some trucks.

Bad plan. Those units are built for 6000LB trucks with 10000 GVWRs or more and and become hyper sensitive in 3500LB cars. Paul makes a variety of modification on the HydraTech units to make them work properly in cars. And they are still very sensitive even after he does his magic.

i installed an astrovan booster in my 66 impala, (have a drawing of the plate i made to fit it) but i bought a new, hydraboost unit for my BU.. ill tell you in a month how big the difference is (and i hope there is a big one with that price difference).. but i can tell you this, the boneyard astrovan booster is miles better than the stock 11 inch vacuum booster was im the b-body
