Brake issue after 8.8 swap

Alright i have swapped in an 8.8 and a new dana 30 front, I have extended brake lines, and have pretty much redone the entire brake line system. The 8.8 has new calipers new everything, I have put the dual diaphram master cylinder and the brake booster from a 95 wrangler on it also. I can get the front to shoot a good bit of fluid when bleeding but the back I dont get much of anything. Pedal is still spongy and i have bled em more than I have ever bled anything and I am at a loss for what it could be, any help would be greatly appreciated. Thanks

Bleed more...sounds like you still have air in the system. Did you bench bleed the MC before installing it? New MC is a huge source of air. You can elevate the rear end and let it sit a while and the air will naturally climb.

Well its a used mc that I just swapped over along with the brake booster. Do you think there could be that much air in there, I'd figure they wouldnt take that long to bleed.

Sounds like a silly question but do you have the calipers on the right sides?? The bleeders on the top?? If they are on the srong side, the bleeder will be on the bottom and you will never get the air out of the system...
