Last week I drove the car, but did not get a chance to work on it. I need to remove the console top and make sure the shifter boot or carpet is not causing the problem? I called Keisler and they were nice, said they would take care of the problem if it is not one of the things above (I forgot to double check the carpet clearance.)
The transmission shifts really nice, so once the fifth gear issue is solved I will be happy with the transmission, and the clutch seems to work way better than my old one. Got on it getting onto a highway and smoked the tires through first, chirped the tires on the 1-2,2-3, and 3-4 shifts
I guess if you installed the trans with the tail tilted down it would fit without cutting the trans tunnel (still need to cut for the shifter.)

My other non-trans issue is the stock tach won't work with the Crane HI-6 ignition...
