I have a b body 833 with shifter and linkage. I want to put the shifter on the od a body unit. Rod lengths are completely different and was considering fabricating my own. Doesn't seem like rocket science but i dont want to crap it up either..
Nice thing about fabricating new ones...if they don't work quite right, you can always do another fabrication.
Shifter linkage isn't hard to make. Back in the day we would fab them up using all-thread rod stock, bend and cut, test fit, adjust, repeat. They usually worked out just fine and I had several sets go for years without issue once I got them right. It usually takes some hard driving/hard shifting to work the bugs out though.
