Let me know if you need a different pic, I can get one for you a little later. This should be a fairly straight forward swap so you can do it yourself with minimal tools. Good way to learn.
Just to rehash you basically have the same side linkage I do no other brackets or anything yours just has that stud/screw through the big hole? Thats what it looks like to me also..the thing I always seem to FAIl on with AT's(and why I like manual valve bodies and 4 speeds) is the linkage set points for the shifts...ive set them up B4 or TRIED and have not got one to work right yet...even when I try to do exactly what I should be doing I still end up messing it up and NOT having it shift into 3rd or the shifts are too soon or too late....and then when I try to get it set "right" it seems to eiter get worse or do nothing lol..the only "succesful" carb and or carb and intake swap ive done was on my 1970 4 speed 383 RoadRunner.....thats just a hook up attach accelerator/throttle cable and go..no ridiculous linkages to screw stuff up lol.
Look at my 2 picture post and the close up of the linkage and give me one like that to reference...one like the guy circled the pin in from a similar angle and closeness.
Also can you give me a pic(or description) of where you routed the hoses/lines that come out of it..I know the front bigger middle one goes to the PCV I really dont know where the rest go to.or if i can just block them off..I wont have to tap my manifold for anything will I? as im using the Edelbrock performer(NOT RPM) not a stock one...i just dont know lol.
