Is there a thread or list for a complete hydroboost with captainfab stuff?

Donít really see a thread with a complete list of parts need to retrofit a hydroboost from an Astro Van or a newer 2500hd.

As far as I can tell I need captain fabs brackets (I think there are two?)
A hydroboost from a 97 astrovan
A master cylinder and reservoir (forgive me if Iím ignorant about how these work together and or the terminology)
A proportioning valve for front disks and rear drums,
All the fittings and hoses (from what I can tell there may be ss an 6 hose and fittings I might be able to piece together?) going to the stock ps pump in a truck lq4 ls

Just curious if someone else had done this exact conversion and would point me to the thread or offer a few pointer on part numbers of where to source stuff.

Go to page 7 of the the link in my signature, post number 161. Your setup will be a little different than mine because your using a metric pump. But I’d be willing to bet you could use all the lines from the donor vehicle because of the pump you have. Assuming this is going into a 67-72 with an inverted flare steering box you’ll have to address the line from the hydraboost to the box.

I took parts from a 2001 2500 hd and noticed that the thread in fitting in the back of the hydroboost organ donor truck had a bigger hole, and obviously the truck reservoir tank had one more return fitting. I've read where you can "TEE" the returns together and use the single return fitting on the reservoir tank. I did happen to use the fitting, spool and spring from inside the pump body. Good luck.
