I know this isn't the right area for.this post, but am not getting replies over there. I have a 1964 2D HT and am looking to replace my TH350 with a Tremec 6 or 5 speed. Are there any camel hump or firewall mods that need to be done to get it in the car? I know linkageand a pedal etc. I justwant to know ifthere are any major mods since I don't have any interior installed yet.
