The master cylinder & booster they are using is very close to the s10's, bravada's, and the Isuzu hombre's ect. around years 98-00 or so.

The only thing I see different is the lines going in are on the engine side rather than the DS fender, but I listed the two different parts numbers below and one is the correct side like DSE shows.

#MC390571 (or) #MC390572 is the master cylinder parts numbers. $104 new on gm parts
used Boosters can be found on ebay for $20-$40 bucks.

I am not sure how the booster mounts up though. DSE may have added something to make them bolt up to the firewall, but it is hard to tell.
