I'm hoping! I'll be running 3.73 gears in it.

Coming along nicely

Getting things mocked up. Need to do some hinge work on the slots to get the doors dialed in yet

Getting a little further along in getting sheet meal hung. Also had to put on tires for some extra motivation.

Hello hevy_chevy67. Happy new year. Is that a true, K5 Blazer, 4WD frame? If so, how did you locate the hole for the Trailing arm cross member? Do you have measurements or a guide? I want to use your blue print. Thanks in advance, Clark.

Yes, my frame is an original 4WD frame.

It was a while ago since I placed the crossmember, but I'm 99.9% sure there was an existing hole on each side I used. I then had to drill the remaining ones. Here are a couple pics I have saved of my front and rear crossmember, the bolts in each picture used an existing hole to get the proper placement and then I drilled new ones for the remaining.
