On an aluminum block with billet steel caps, I could see where you might run into galling or shaving the block during install. Would suck to have some aluminum shavings between your caps and the block.
Mopar to the bone!!!

I asked this same question to that jerk wad Russ @ Indy when he was at The MATS a few years back.. His answer: Yea, It's called a slide hammer and a rubber mallet..  Typical response from the jerk.. So we made our own puller, and use a plastic mallet with frozen caps with zip ties to hold the bearing in place until you can get a nut on the stud..  Not too bad when the caps are frozen..  I believe BigCube made his own press type installer.. Chris..

The only problem I see with that tool is it would have clearance holes for the 3/8 bolts(looks to be 3/8) and the way they bolt down on the bottom plate you can be on a angle and be worse than just tapping the cap on

I m de my own bridge. Bolts to the pan rails. I use a 1/4 threaded rod, a large washer and a nut, pulls the cap right up. I then bolt a harmonic balancer puller and use a small block of alum to prtectect the cap to push it down. It works very well. I'm sure it is similar to the tool Kbps sells, also I lube the sides of the caps to help them slide in, never put them in dry, no galling at all
....BAD A$$ STREET CAR.....

The bolts that hold the top plate in place are the same length. The end of the bolts tighten up until they hit the pan rail assuring they are same height on both sides.

Putting the main caps in the freezer the night before should help. I plan to make my own installer based on BigCube's picture. Swapping out the center screw with a length of threaded rod and a nut will make a nice remover, but I bet the old slide hammer works fine for removing them.
I just want to take great care with the ductile iron caps and the aluminum block with the KB fit.
Just a side note, the KB caps have 5/8" studs in the block that are stepped to 9/16" through the caps with a 5/8" part sticking into the cap slightly. What a difference compared to a factory BB cap (attached).

Take the studs out and put long threaded rod in its place. Use fishing line or ribbon to tie the bearing in the cap. Nuts and washers on the threaded rod and evenly draw the caps down in place. Then remove the line or ribbon. Simple.
