Levelers for a Series 1 J-head

[oldmachinegary]

I'd like to add some levelers to the base of my Series 1 J-head Bridgeport. I've got it setting on four pieces of oak flooring which doesn't allow me to do any leveling but keeps it off the concrete. I've also heard some of these levelers have rubber in them and help isolate the machine.
Any favorites for the Bridgeport? If you have a brand in mind and an approximate cost, that would be great.
I don't have the equipment to lift the machine real high but I should be able to get it up high enough to slip the threaded style in.

Thanks very much.

saw a picture recently of a bridge port where they took a piece of 3/4 thick x 4 strap across frt. 2 holes in base to put levelers outside of base so they are easy access, I have seen those levelers with rubber in the Grizzly catalog. Hope this helps.

These are what I use, 5/8 bolt for Bridgeport I think

I made my own with some 3/4 inch threaded rod. I tapped the existing holes and screwed in the rod with a jam nut and a pinned acorn not on the top. Here is a pic.
