I could, but I didn't make any drawings or notes. I'd have to wing it, again, with the truck close by.
I can recall that the top bolt is 5" long and the bottom bolts are 3.5" long. Rarely have I encountered anything from GM that uses 7/16 UNC bolts, but these are that. Ford uses 7/16 bolts semi-frequently, but they are very rare in GM stuff so I found it interesting/odd that the Saginaw mounting bolts were 7/16.
I gave a LOT of thought to having Lee PS add ram ports while they had the box. I decided not to for simplicity's sake. I may end up regretting it, but the
Snowball project has made me a little gun-shy. They can always be added later if it proves to be the wrong decision. I did have the PS remote reservoir made with an H-B return port on it.
Next up is fitting the Borgeson steering stuff. The answer to my question above is, No, the column's shaft can't come out the bottom with these SBC engine mounts. Maybe with the original mounts but I've no idea what those look like. Looks like what was there originally was one of those GM telescoping u-joints that are similar to a FWD "tripod Joint" in how it works. The pin for something like that was still there, as was a thin walled tubular spacer. Neither of which wanted to move, and with them in place the shaft wouldn't go out the top thru the clamp or the support bearings. Hacksall to the rescue! I opted to add a splined section to the bottom of the column's steering shaft for the connection to the upper u-joint. I was planning on cutting the column shaft anyway as I want to put the upper u-joint as close to the lower support bearing as is practical. My idle brain time is currently occupied by figuring out how I want to design the join of the splined shaft to the bottom of the column's shaft without increasing the OD such that the shaft can't be installed from the top. The column would need to come out to install the shaft from the bottom. That's not the end of the world, but I'd rather not if I don't need to. If only to reduce risking further damage to that escutcheon around the column at the dash.
