I never really had full clairity on what I was going to do to accomplish making my blazer a full on driver. I just felt this was a step to the rite direction.. So some of you may cringe or think I should have done it different.. Believe me. Some times I think the same things.. But I just am still plugging away at it.
Here is the only pick of the 71 GMC on the blazer frame I managed to get.

But back to the frame works:

I accually accuired the 75 frame in 2006 so it was a long process getting it to this point. I also had come across a 350 that ran for 45 buck. Since the 454 needed some work and i wasn't sure I wanted the bad fuel economy I used the 350 and T-400. Plus the rear axle of the 75 was a camper special (big brake drums) in great shape I also used it. The other one wasn't good at all. So I cut the mounts off rewelded the 71's to the 75's and put an ECE super track bar on her.

Drivline is done so time to put the frame back under the blazer to test fit it all

Everything seemed to work out great with body mount swaps and clearances. Exept the front frame horns, they are very different. So I cut the old ones off and did what I could freezing my butt off just wanting to take it for a drive and get done before the snow came. Yeah I didn't do very good with that portion. So I still have to rework that to this day. I still think I want to keep my front bumper and not go roll pan in the front.
