Look for the list number on the carb and that will tell you what you need. Holleys go by that number for the kit
 
If the # on the choke tower is 80870, that's what you need to find the correct kit.

Easy to check the vacuum diaphragm. Take the diaphragm housing off, suck on the apply hole, watch/feel how the rod moves completely. Then depress the rod completely, hold finger over the vacuum hole, if the rod remains compressed, you are good. My opinion.
 
Thanks guys!
I can work with this..
