If my future investigation warrants keel bracket replacement, do those of you who have done this think this will work?
My Plan
As my boat is on a cradle, this will differ from your trailer methods.
Step 1 - Support keel on jacks and wood rig that I will make
Step 2 - Pull pin by whatever means are required. Disconnect keel cable
Step 3 - Lower keel with jacks and wood rig until it contacts cradle cross member, seen here:

Step 4 - Use a to be determine means (read: 87 small block Caprice and a tow rope) to drag keel aft along cradle cross members seen here, sorta:

My theory: if I can move the keel aft by three feet, I should have access to the keep pin brackets and pin without actually removing the keel entirely... right?
Total keel movement from its stock location should be about 8 inches down, and three feet aft.
Questions:
1 - Do you think that will be enough to access and replace the brackets?
2 - Does anyone make the brackets anymore? Or, does anyone have an accurate drawing I can give to machine shop?
Thanks all!
