Lee is local to Northern Illinois, but Napa sells everything they do.

I am about to do this myself. I picked up a drum/drum setup from a board member (bracket/rod/booster/mastercylinder). I'm thinking (hoping) there is enough play in the brake lines you can do the swap without actually disconecting them from the mastercylinder. Looks to me to be the same master on both power an manual with drums.

yes the master would be the same for power / manual brakes
only time the master changes is from disc to drum..... use this site to check interchangeability http://www1.autozone.com/servlet/UiB...n=viewHomePage |

Its a pretty easy addition, and you do not have to disconnect the brake lines from the master cylinder or atleast I didn't have to. There is an extention wire that is needed for the brake light and I don't have one of those so if anybody has one I would be willing to purchase it.

Dinnut, you are probably going to have to adjust your brake light switch. It is a pain, and I made sure my two boys weren't around to learn any new words while I did this.
This is the easiest improvement I have done to my truck, I recommend it to everyone!

I am in the process of doing this right now. Seems to be pretty easy but am not sure.
I bought the stuff from a board member and it came with two brackets. Where do these things go? And where is the best place to hook up the vacuum, right behind the carb on the intake?
