Picked the base up for the handle I have. I have a MGW so I dont need this. Pro50 short shifter for a TR3650. Springs are nice and tight. Has some gouges on the base but nothing that effects it and you don't see that part anyway. $110 shipped!
No idea how old it is honestly. I bought the handle on here and bought the base off a guy on Craigslist. The springs are still like new and it snaps back to center just like it should.
