ongoing saga...I have it almost figured out :-) picked up a standard unit to investigate the modifications that were done...(pretty interesting repurposing going on) If anyone else has delved into the unit, I'm looking for ideas on what may have been used (see arrow on the right) as it is the most corroded piece to determine measurements or the actual repurposed item that was used. It appears to be a simple ring to keep the inner shift lever in place even though a roll pin is used on the opposite side and keeps the actual shifter handle from traveling...on a lighter note, the box cleaned up nice.
