Nice work BB! From what I can see from the pics you have done and excellent job and keeping it as original as possible.
Do you have a 2sp power-glide? I would recommend going to a TH400 Hydromatic 3sp transmission. I have a core if you need it. I have a guy in Southern Alberta building 3 of these TH400's. Very stock but stronger and the driver has the ability to shift the transmission manually along with a 2400rpm stall. Makes you a bit of a sleeper but wakes up at the line an crushes the daily driver or street [censored] with a 4sp.
