That amc 20 I'm keeping in my pile of 4.10 axles lol....
Bought spring perches today and I'll shoot by the Jy to grab the parts for a disc brake swap from a liberty/grand Cherokee...and if the price is right I'll grab the wj booster and master cylinder to do the swap...

Quick hydraulic theory lesson for you guys. When you move fluid from a large area to a smaller one, the pressue increases. Now increasing the size of the vacuum booster isn't where the pressure comes in, it's in the larger bore of the master cylinder. Its piston holds more volume than the MJ/XJ unit creating more pressure to the lines.

Adding the wj booster and master cylinder adds the extra boost to push the hydraulic fluid as mentioned above from Lee to make a difference in braking...
It's nothing like a race car type but BIG difference from single to double power boosters...

If your looking for more braking power out of those 1 tons...I've seen in this thread where the guy used a dodge 2500 brake master cylinder to help with braking....

Good morning fellas....
Thinking the fuel pump is going out in the Cherokee...
When cold stupid slow cranking until it catches pressure/power/ or something to make it crank faster after it catches something...then starts
I was at a Walgreens yesterday when it didn't want to start...
If it doesn't rain today I'll be double checking the starter cables from the battery if there's enough connection to start....
If not there's $170 to a new Bosch pump....
Which sucks because I just put in 18 gallons of gas yesterday morning
