'68 Firebird Axle & Pinion Bumpers
Left (drivers side) axle bumper and bracket for my 1968 Firebird. This being the '68 bracket type with the bumper mounting hole 3/4 inch from the frame. The Pontiac Parts books also indicates a second type with the hole 1 1/8 from frame. The '67 had a smaller bumper mounted on the bottom of the frame rail (holes somewhat visable right of shock in picture below)
The Pontiac Parts Book labels the bumper in the picture to the right an axle bumper in one place and a pinion bumper in another.  It is located above the front of the differential.  This is about half of factory original which has broben off.
I have not yet found any of the Firebird new/resto parts vendors offering these parts.  I just received a replacement at D&R Classic Automotive from their Camaro Catalog. The width is the same as the original but I don't know how close the replacement is to the original.
