Lippert Schwintek Inverted Bearing Blocks

These are models of the bearing blocks used in a Schwintek inverted slide system.  It is very hard to buy these and they are expensive when you can find them.  I was able to find a set on ebay from a scrapyard in order to fix my trailer.

These need to be made from aluminum.

This is a work in progress.  Both upper and lower blocks have been modeled.  I still need to model the plastic guide shoe.
