42RH / A-500 in a Duster with pictures.

Still researching a 42RH for my sons 69 barracuda. I have a list of what i need to install this trans, only hang up question i got left is what everybodys using for a kickdown linkage? Should i use a push-pull cable type arrangement from summit? This will allow the use of a taller intake later on. I have an eddy streetmaster i just got (thanks txstang84) or should i use a stock A904 arrangement. Only vehicles i can find the A904 V8 kickdown are late 70s volare /aspen. Not sure if that will work with A body.
