K20 box mods

[burnin oil]

I cant remember the companies names but there are a few that rebuild the boxes. A little searching should tell you who rebuilds them and mods them. I put one in my Dodge and it was around $400 shipped. Chevy should be about the same. Some of the companies mod the pump to ensure full flow but the pumps are pretty much universal. Many manufacturers used Saginaw PS pumps. Nothing special about them. Basically the fittings, some metric, some standard, and some have o-rings.
