Hurst Shift Levers wanted, RAM ROD
The Ram Rod forward-gear levers are the same as those used in the aftermarket Comp Plus and Street Super Shifters (install kit #363 8617). I had no problem finding the numbers you need, both used and NOS. They pop up on eBay pretty frequently (I still have saved searches for 'em for some reason). The 3894 was also used as the 1-2 lever on the B-body aftermarket Hursts (install kit #373 4089), so that one in particular is pretty common.
I have a couple of reinforced rods here from an unknown application. Are there numbers stamped in yours, or shall we do the tape-measure boogie?
