The damper piece, is from LMC and matches to original in dimensions. Assembled as it was and per LMC' s parts diagram..The larger firewall side slides into a tube and is fastened by a hex screw threw the tube and rod. There is a 90 degree bend at the other end that slides in the vacuum controller
I could do a hack and open up the bushing a bit and epoxy a short brass tube to it to receive the damper spring rod but it is not my first choice.
