Re: Hydro boost or regular?
Any year of the Astro vans have the same system and will work. If the hydra unit is installed in the same clocked position as it was in the van, both stock pressure hoses for a mid 80's full size Buick w/diesel will fit perfectly ($28.00 each). If you clock it 180 degrees from stock new custom hoses will be needed. The unit will work either way. I used a steering pump from a 30 series Chevy van that has the dual return, low pressure inlets.
OLDED - It's STOCK if it's made by GM and it fits!
