I think 64s still had drop out rear ends. I know that 65s were different. I would like to see more pics of that 64! I also wish that I didn,t allready have a th350 I could use the full second off my 19.13 time! What would it be worth to change first gear on the th 350 to 2.75 or 3.06? The cost is about $500, I wonder if its money well spent. What kind of 1/4 mile time and speed would that 64 be expected to run? Jay 6155
