Steering column question

I have a 1965 Impala 2 door that has a 396 with a power glide transmission. I've been thinking about installing a TH 350 transmission. Does anyone know if the steering column from my car (tilt, power glide 2 speed) will work once I install the TH 350? I already purchased the linkage that is located outside the firewall (in the engine bay) that attaches from the column down to the transmission. The linkage is for a 66 TH 400 car and includes all the connecting rods, bushings, brackets for the transmission, 3 speed column lens, etc.. I'm just not sure if there is enough room in the column shifter to compensate the extra gear I am adding. Any advice would be much appreciated!

Same colum was used for all three automatic transmissions. Only the silk screen on the speedo changed to add the extra gear the power glide is missing.

The linkage is what is different between transmissions and a TH400 or a TH350 linkage should work fine (the TH400 is a wider trans than a TH350 so your linkage may be a little bit short, but I am sure you can modify it to reach across from the frame to the tranny to reach the smaller TH350).

Big Dave,
Thanks for getting back to me. I'm glad to hear the column will work. I actually have the three speed automatic lens that has the extra gear present. Any opinions on which transmission to use? I'm not going for anything crazy power wise - thinking about the Edelbrock Performer RPM top end kit. Probably around 450 horse when it's done? Do you think the TH 35 will be ok if I have it rebuilt with high performance internals? This car will be strictly used on the street - not going to race it.
Thanks again, Fran

Edelbrock Performer RPM top end kit will yeild about 0.9-1.3 horsepower per cubic inch depending upon your carb size and the cam choice so you are looking at a range of horse power from 315 to 455 horsepower. The bottom end doesn't make horse power (for any given static compression), it buys you reliability (peace of mind).
