OK guys....the guy doing work on my Challenger tried to put the T-handle slapstick shifter on and he says it wont fit .....problem: the shaft is a round one and t-handle has a squareish hole and he said it won't fit . It has the ball shifter on it now.....Question: where can I get a different shaft part that the T-handle will fit OR how do I make the T-handle fit??
I saw some instructions on an Ebay listing but can't read the whole thing....anybody have the instructions
Pics attached of what I need??
