1993 RR Power Brake Questions???

Our son has a 1993 LWB Range Rover that he wants to convert to a R380 5 speed.
He is running an intercooled 2.8 liter Isuzu Trooper Turbo Diesel 4JB1-T engine and wants to replace the ZF-auto.

We've never swapped out the power brakes before, but it looks like they would be in the way of the petal assembly. I would think there were manual versions of the LWB RR that had the same power brakes and would like to keep them as they work fine, but thought I would ask if anyone had removed the power brakes and used a master cylinder?

Thoughts... am covering new ground here, at least for us.

There are at least a few manual trans 93-95 RRC. Bear valley had one for sale around 2000 and said it was factory. It was a 95 green SWB, but the brakes between SWB and LWB are the same. I would start by finding the pedal box assembly out of a disco I with the r380.

We have a 5 speed Disco here and looking under both hoods tells me that we may need to loose the power brake assembly on the 1993 LWB RR and go with a master cylinder and booster from a Disco or earlier RR. We may have to swap some of the brake calipers as well, but am not completely certain at this point.

Shoot a PM to Rovingbeetle, I know he removed the zf in his 93? and is using an r380. I know he's using everything from a D1 5 speed but I don't remember what he said he was doing with the brake setup, and he is also running a diesel, but an Isuzu IIRC.

When using "Rovingbeetle" under advanced search, it comes up with:

Invalid User specified. If you followed a valid link, please notify the administrator

Any suggestions?
