Either Brewers performance or Passon performance might have a reconditioned one, nothing new out there.

I got one off E bay out of CO. For around 500.00 plus shipping. It had been gone through. But I opened it up and checked every thing it had assimilable grease every where in side. You can look around and find a pretty good deal sometimes. I think I did.

Rusty is yours an 18 or 23 spline input? I have an extra 23 spline but the 18 was used on 440 and Hemi cars and cost considerably more

I am good to go their Bob. Was telling the other guy how I found the one I got. Mine is the 23 spline. In put shaft is good and the out put is good no bent or deformed spines as well no ware groves on where the clutch ride's was really impressed with what I bought. The darn thing looks as if it never was used. What I was saying is that since it was put back together it never even was put into a vehicle. The story on mine is that I guess that the guy I got it from has a shop or transmission shop he said an old guy came in and wanted the 5 speed Manual put in Not the one passion build's but the other one. I guess that he got this one after he installed the 5 speed for the man. Thinking he knocked off a little money and got the one I have. Thanks Check out who was asking where to get one. Russ.

I’ve put a 5gear from Passon in mine. I do have the hemi 4gear and Hurst (would need handle and knob) that came out. I reused the handle and knob. I do have an extra Hurst T handle.
Haven’t considered selling, but the figure Qbird mentioned would get it.
No issues at all! Just wanted better road touring gear ratio.

What is the most obvious difference that one can see to show if a 68 roadrunner was a original hemi car ??

The main shaft i mine has to be changed, and when the car was running the 3rd gear slip out when you let your hand on the knob
Didn't opened it yet but was thinking on rebuild it. I have at least to change the main shaft because it eats the speedometer gear pinion...
What are the plans for yours Bob? Would you consider to "tear it apart" or want to sell as a complete unit if you have or want to sell it?
