50 Cevy , I put a T-5 in my 41 , It is'nt that hard. You do need to grind some off the input shaft , and you will need to get a new clutch disc. And probably there won't be enough splines on the input shaft to completly release the clutch. But , you can get past that prety easy , either add splines to input shaft , or grind off some of the splines on the cluth disc. I recently herd that a Jeep Cherokee disc will fit without modifications. Good luck
