Cool...do you know what years the Dana 60 were put into the squares? Are they a direct bolt in? Or will be be doing mods? I'll try searching the internet for this, but if anyone has first hand experience it would be cool to hear. I have a couple of update on the build since my last post. I...- grampsbutler

Hey Big Ray.....the 10 bolt is something I have been pondering recently, and I don't know which direction to go. The 10 bolt has stood up fine so far but I don't want to stick with it long term because 1: the brakes are slightly small for running 37s, 2: I will likely break something in the...- grampsbutler

Vintage Air, Dynamat and Carpet: Over the long weekend I was able to get the Vintage air system into the vehicle. On the whole the install was pretty straight forward, but there were a few surprises.

Electrical Gremlins: I have been having intermittent dead pedal. I am pretty sure that this is not an electrical connection issue because as soon as shut it off and restart I get my pedal back.

Intercooler relocation and grille install: I had to move the intercooler, because it was interfering with the grille. This was a minor tweak, where I had to move it back by ~3/4" at the bottom only. Even with this movement, there was no room for the stock grille, without witling it to provide...- grampsbutler

Hydroboost, ps for cummins swap - help!
I am closing the loop on this for the benefit of others who may have the same issue. The problem was with the pressure regulator inside the dodge pump. If you take it apart there is a nut holding the high pressure relief spring valve in position. It had backed out which caused the pressure...- grampsbutler

I am with you.....I knew it was going to be a challenge. This is my first build with electronic controls so I am learning as I go.

Its Alive! This past weekend was a big milestone. I took the maiden voyage... I put the fuel pump into the tank.

Maiden Voyage! I got the drive shaft in this weekend and put the fuel pump into the tank. I got it all plumbed and took it for its maiden voyage. It ran great while cold, but then it died on me repeatedly as soon as it got close to operating temperature. It started to loose power, and then...- grampsbutler

Here are some pictures of the set up..... If you look very carefully, we had to bend the lower mounting tabs to set the intercooler into the cavity behind.
