I could not get the 37 bellhousing to work correctly with a 38 and up clutch fork since the hole for the ball was closer to the input shaft causing the fork to go over center on the throw out bearing and when everything heated up the clutch would not want to work,post some pics of the clutch pedal and linkage you have so I will know what you have and what you will need to get. If you cant get a 38 to 46 bellhousing you can make the 37 pedal,linkage and fork work by welding some fingers on the 37 fork to work with the later throw out bearing,I done that originally with my 37 untill I found a 41 in a junkyard that donated its bellhousing and related linkage parts and got changed again when I installed the t-5.
