this is a on a new to me '68 383 with a Summit 08600VS (600cfm) 4 barrel, 4 spd no a/c. Seems to be running OK but not crazy about this return spring setup - especially attachment to carb - I count 38 coils on that rusty spring, fwiw. What do I need to get to to make a better setup? I see classic industries has some brackets and springs - not sure what would do the job. thnx for any comments.

That front bracket looks homemade. Your spring should have a little more tension on it. Try Jegs. They seem to have better prices on that stuff.
This is the set up I like using. They make one for a 4150 style Holley and another for 4500 style.

Why not get the correct parts ?
The spring and bracket can be had for a little over $20.00.

I like using a double spring. I have had one break before.
As mentioned factory original stuff works perfect. I've got it dbl springed

You need a Holley 20-7 throttle bracket adapter also.

"No big deal,' ALMOSTY ANYTHING WILL WORK u can make one that will work , and prettier. A double spring is safer, but need a lighter spring if doubled .Don`t worry too much about it !

Already checked them out. Didn’t see any had the dual return springs.
There's 3 pages of dual throttle return springs on the Summit site.

OK
I run a Holley dual spring set up on mine. Works good but it is on the stiff side.
Very safe, good idea

Mopar didn't have dual springs until the 80's may be.

I like it; it's a simple solution to the poor pull-angle of the throttle cable. With too much spring, that angle will eventually wear out your base plate at the throttle shaft. Whoever built that I think was thinking long term.
But I would fix that pull-angle as soon as possible, and get the proper Mopar adapter at the control-arm. Notice Ironmike's solution in post 11 which puts everything in a straight line
