The Moog K201285 are sintered metal, the OTTP are aluminium which might not last a winter or 2

Pulp by fancy bushings did you mean the Moog problem solvers?

 

Imported from the same Chinese factory. One more time: Moog is a brand NAME in this century, it was different in the last century before corporations started selling names and making money by going bankrupt. They print pretty boxes now, and have the same catalog errors as everyone else.
Owned and managed by DRIV inc. which is a spin-off from Tenneco. Tenneco was bought by Apollo Global Management. Before that Moog was owned by Federal;-Mogul; which Tenneco bought out of bankruptcy. Tenneco then went bankrupt and started selling and spinning thing off.
They operate just like any other parts supplier, buy from the cheapest factory that makes the part to the specifications then put it in a box for sale.
