Not much forward progress lately.
The IRS is mocked up and tacked. I made some templates for a bigger notch and those are at the fab shop getting cut.
I spent about 6 hours in the car over the last couple days and most of it was spent thinking of where and how best to mount my compressors and air tanks. Spent a little time tonight mocking it up.
I plan on drilling some holes for my leader hoses to go through the cross member to the tank.
