Lmm ps pump in lb7??

[BigdaddyCtrain]

So i thought i read of puttihg a lmm hydroboost in an lb7, but now i cant find any threads on it. Anyways i have to replace my power steering pump today and i was curious to know if i should try putting a lmm one in. I dont know if they would even bolt up or work right, or if they're even any different, but thats why i need your guys input. Also curious about a master cylinder too, and confirming the hydroboost. Any help would be great!

They are the same from 01-10. Only difference is the lb7s had a black resivior and the lly up had a silver one. I've ran everything from lb7 to LMM on my old LLY. Hydroboost will bolt directly up as well and is an upgrade to the older ones.

iirc, Ben put an lml hydroboost on his lly and said it works awesome.

You post header states P/S pump and you ask about a hydraboost, IIRC GM went from a 10 vane P/S to s 12 vane pump in the early model LML. GM also switched to a 670-680 series gearbox in 2007.
