[QUOTE="Walt Jaquith, post: 425274, member: 18654"] There's several different paths to upgrade the yj's notoriously spongy brakes. You can go with a dual diaphragm booster from a '95 yj, or there are a couple others that folks have modded in. The most popular master cylinder swaps seem to be either from a 85 Ford E350 or a Dodge Ram 2500. I'm going to pull the whole setup from my 91 S10 Blazer doner, and just hold it up there to see if it would fit and what it would take to mod it in. If it's not a lot of trouble, it would be worth it to have all the 'new' stuff coming from just one rig. Easier to keep track for maintenance. The 4.3 is almost 100 lbs lighter than the Jeep 4.0--one of the reasons I wanted to be rid of the thing. It's also considerably shorter being a V6 instead of inline, so I could probably bring it right up to the radiator without adversly effecting weight distribution. As it is, the entire engine block will be behind the front axle; just the bracketry and pulleys will be forward of that. There's going to be a *lot* of room between the engine and the radiator. The little torque converter tab is how you get them from a rebuilder. This is the second tranny I've had rebuilt, and they both came with them. [/QUOTE]
