Right now I have two problems
No rear brakes
And it shakes pretty bad under acceleration
when are you going to finish your front bumper?
Do you have a better shot of how the exhaust is run at the end? Did you go under the frame over the leaves, or what?

Do you still have the stock combo valve (under the master cylinder, contains the proportioning valve). They are designed to "trip" if they sense a loss of presssure to either the front or rear axle and will close off the fluid to that end.
