none of the kits are for "Chevelles" per se, none of the instruction sheets include Chevelles and none of the boxes mention Chevelles

Nova kits, 3 different ones, 1 V8 for 65-67, other 2 are included with the Camaro kits

Camaro / Nova kits 2 different, small block & big block, none for 6 cyl

big car, small block without ps
big car, " with ps
big car, big block
trucks. 2 kits, w & w/out PS
vans

I have never seen a kit that include the Chevelle models and I have had tons of these things (still do ...)

I am sure the reason was the throttle CABLE, vs the ROD as stated above.

Again, I have never seen an instruction sheet mention a Chevelle nor have I ever seen a kit for the Chevelle.
