I would be very interested in the details involved for installing the hydro boost. I'm considering this conversion since I currently have manual disc (requires considerable pedal pressure) and would like to avoid the bulky vacuum units. Thanks in advance, Bob
Details are pretty simple. General parts/price list:
Hydroboost from 01 Mustang GT - $110 on ebay
Master cylinder from the same - $35 on rock auto
metric (forget size) to 3/16th adapters x2 - $5 at O'reilly's
High pressure hose from P/S pump to hydroboost - $50 at local hydraulic hose shop
High pressure hose from hydroboost to steering gear - $50 at local hydraulic hose shop
3/8 low pressure line from hydroboost to T-fitting - $5
5/8 hose from gearbox to T-fitting - $10
5/8 hose from T-fitting to P/S pump - $5
3/8 x 5/8 x 5/8 hose barb T-fitting (made with pipe fittings) - $10 at home depot
3/16th lines from master cylinder to proportioning valve - $7 at O'reilly's
Total ~$290
Notes:
the locator pin on the hydroboost needs to be knocked out
1 hole needs to be drilled in the Hydroboost unit mounting plate for the lower passenger side mounting bolt
1 hole needs to be drilled in the firewall for the drivers side lower mounting bolt
the big hole in the firewall needs to be enlarged slightly
the linkage needs to be modified to fit. The Mustang linkage is too short
the linkage will bolt to the lower hole on the pedal. That is due to the angle difference of the master cylinder
Cautions:
the Hydroboost unit has metric o-ring fittings. The original high pressure line will bolt in...but will NOT seal
Make sure your proportioning valve will work with your master cylinder
Overall it is a very easy conversion. I never drove the car before (single pot drum/drum) but it is nice to drive now. I would consider it bolt-in except for the push rod.
If you have any questions feel free to ask.

Very cool build! I've got a 63 plymouth 4dr I started working on but then traded a ford to a 65 coronet. Can't decide to go 318 poly or 383.
The 440 fit with PLENTY of space. Tightest part is the hood to carb clearance. If you can get the big block for a similar price I would definitely go for the extra cube. You will definitely need the bigger torsion bars and a sway bar with the extra weight though!
And now that the car is running we found out how bad we needed the suspension upgrade. There goes another $460.

And finally the UPDATE
The car is running and driving. For some reason it has a tendency to run on after the key is turned off. It is and electric problem though, not dieseling. I am still working through that.
The thing runs well and will move in no time flat. The .88 torsoin bars are going in favor of some new .96 bars. We are also adding a Hellwig sway bar and getting 2 new tires for it. That should deal with the extra front end weight.
Radio is in and working and rear speakers are going in today (My brother is working on it while I am at work).
We are having trouble finding a place that will do a decent job aligning it. Doesn't seem to be many reputable places around here and chains like Big Brand have a tendency to charge you while they figure out what they are doing. It is close on toe and camber but I need to check caster.
The exhaust was done a bit ago but I never mentioned it. 2.5" back to 3" Flowmasters dumped just in front of the rear axle. It sounds AMAZING. It is going to get loud on long trips though.
We have the weather stripping coming for the windows. For the doors we are using OE weather stripping from a '92 dodge truck.
Still need to put in the brake light switch.
Other than that we are just finishing up little things before my brother is going to head out.
