I finally figured out how to go about bolting on my passenger side front spring mount and got the driver side on.
Here's the driver side.
I thought I had a pic of the passenger side but I must have spaced it. The problem I had was the front was about a 1/4" lower than the back which would probably cause problems when I go to mount the core support. Sometime in it's past, someone had welded the bottomg part of the core support bracket to the spring mount...guess the rivets weren't strong enough...which is what I'm thinking is causing my problem. So I did some grinding and have the bracket bolted together and will do some final adjusting tomorrow. IIRC the top of the original bracket for the core support was a little higher than the top of the frame. I'm mounting the 4x4 ones flush (or maybe a little lower) to give me some room for adjustment. The original bracket had a 1" hole (approximately) and the 4x4 ones have about a 2" hole for the core support bolt. So I'm hoping by mounting them a little lower I have room to work with when it comes time to deal with that.
Then I get to fix this vision of nastyness...the passenger side is just as pretty.
I pretty much have it figured out, I'm a little nervous about doing the repair...never done this kind of repair work before. I've also discovered the rear shackle mount needs to be moved towards the rear of the truck more. So I'm going to make the hole for the mount a little longer (front to back) so I can get the mount where it needs to be and then weld in a filler piece in the frame and then put on an outer plate to make it stronger.
From what I've read, the shackle needs to be a little more towards verticle than it is now. I found on a website some info that says that when a straight line is drawn from the front spring eye to the rear spring eye, the shackle should be at a 90* angle to that line at ride height. So from what I can tell in that last pic, I think the rear mount needs to be moved back a little. Every shackle I've seen on the front of a 4x4 truck is pretty much verticle so I'm hoping my thinking is correct.
