Thats the original trans x-member. I think I'll move it forward a few inches and use it as is. The original trans mount on the 4500 looks pretty beefy and straight forward. I'll probably have to fab a spacer to get the height correct.

The springs are from the 86 one ton (m1008). I think they are 47 inches not 52. I only had to move the front/rear positions 1.5 inches out.

I modified the front mounts with 2 inch steel blocks and used 2 inch longer shackle hangers from ORD. This kept the geometry the same and raised the front 2 inches using stock springs.

Steve- I have a serpantine setup and will be using electric fans (Spal-dual 10inch). I plan to twin stick the 205 and fab the bracket/shifter setup so thats not an issue.

Thanks, Mike
