JOHNNY BOY37 -
I have a 37 pickup and have set it up with a T-5 transmission.
First, I'll answer your question. I used a 40 pedal mount bracket to reconfigure my pedal set up. It worked, but it wasn't exactly like the 37, although it was close enough.
Let me go a step further and tell you that you would really be better off if you used a 38 to 40 bellhousing, and even at that, there will be slight differences. The reason is that the 37 clutch fork ball is closer in toward the middle of the bellhousing than the 38-40. This causes you a problem because the only clutch fork that will work on a 37 is the 37 clutch fork which uses the old style graphite throw out bearing. The fork can be altered to be used with the new style bearing by using the fork arm and the 38-40 fingers. The fact that the clutch fork ball is closer to the center of the bellhousing will cause you some problems because the physics of the set up does not enable you to adjust the clutch as much as if the clutch fork ball was back further as it is on the 38-40 bell housing. The best bet is the 38 bellhousing, clutch fork and pedal set up. If you use a newer bellhousing, you will have to use the newer fork with it. What I can't tell you is if all of the pedals will enter the floor as correctly as they would with a 37 bellhousing. I do know that Junkyard Jeff on this site has installed a T-5 in his 37 and I believe when he did he used a later set up. You might check with him.
The last thing I can tell you is that you might be able to move the clutch ball in the 37 bell housing, I was going to do that on mine and, but didn't. I had finished the project, or so I thought, and I finally worked with my clutch adjustments until I finally got it right. If I ever pull my engine or do any major driveline work, I will probably step up to the more correct bellhousing.
