yep eddie sells the mopar throttle adaptor and you use the throttle stud from the 2-v carb to hook the cable and throttle pressure valve linkage up

most times you can lengthen the TPV linkage from intake bell crank to the carb 1.5" or so and bend it around and make the 2-v linkage work

this is important to keep the tranz from burning up and to have the shift points set correctly

when you go from the SB to the BB you will need BB TPV linkage for your yr b-body

I dont thin any of the SB stuff will fit or work for the swap

I sugest you locate these parts before swaping in the BB along with the BB tranz

you shift likage should hook up from SB 727 to BB 727 with maybe some adjustments..IIRC

most important is to have the throttle pressurevalve linkage hooked up and adjusted correctly

thats the most important thing on the auto tranz
