3sp on the floor to 4sp

I went from a 3spd column shifted manual to a floor shifted 4spd in my Barracuda.

The 3 spd bell housing only had the 3pd bolt pattern so I needed to pick up an other bell housing. Both the \6 4spd bell housing and the v8 bell housing I am now using have bolt patterns for both 3spd and 4 spd. If you crawl unde your car and look at the surface where the tranny bolts on and see another set of bolt holes outside the 3spd pattern you should be set to go.

There are two body style 4spds, the short tail shaft for A/F bodies and the long tail shaft for B/C/E bodies, the long tails shaft unit also came in pick-ups and vans. The long tail shaft can be used in A-bodies with very little extra work. I have the long tails shaft in my A-body Cuda, I needed to fabricate a bracket that mounted to the rear tranny shifter pad and positioned the shifter forward to the A-body position and have the drive shaft shortened approx. 3 1/8".

Most all the 4spds have a bigger output shaft (have heard of but never seen one with the smaller output shaft) so you will likely need a new slip yoke. The other thing to watch for is the hemi and 440 car 4spds have a bigger 18 spline input shaft, it you happened to luck into one of those you will need a minimum a new clutch disk with the 18 splines and a new through out bearing that accommodates the larger bearing support sleeve.

If you need a shifter the Hurst Indy shifter is a steal. For $150 from Jegs or Summit you get the shifter, rods, levers for the tranny, mount and all the harware and clips. Only down side is the handle is short but it is a bolt on so a different handle is as close as the nearest swap meet or you could likely adapt the handle from your 3 spd.
