Transmission Swap 1967
Short answer: From a Powerglide, a Turbo 350 is a straight swap; a Turbo 400 needs a new crossmember, a front driveshaft yoke, and a shorter driveshaft (and the kickdown may differ by year).
A member who did the 400 swap in a 1967 convertible adds: the 2-speed shifter has too much throw, so fit a 3-speed unit or a conversion kit with the right detents and linkage rod (and replace the plastic indicator) — the extra third gear is well worth it. He sourced the crossmember and driveshaft from Steve Hansen. Note: a “Turbo Glide” and Turbo 400 are essentially the same physically — the 400 uses a carb kickdown cable where the Turbo Glide used an electric switch.
