Where would I look online for C4 1976 Thrust washers?
I need more variable in thickness.
The small one is .074
Bigger is .054
And the Plastic is .123

I need less. It's to tight :/
What are my options?

I was there not long ago. Call Transtar - link below. They have locations all over creation and also do mail order. They sold me a thrust washer “kit” that was comprised of maybe 8 different thicknesses.

My local store was staffed by very knowledgeable people. Dude k we exactly what I needed and had the parts from another location the next day for me to pick up.

You're only going to find selective sizes for the small one (#2 washer) and the plastic one (#1 washer).

You need to first figure out what size you need for the #2 washer before you can tell the size needed for the #1 washer. Do this by assembling the c4 with a thin #2 and no #1 washer. Measure the endplay at the input shaft while forcing the gear train forward. I think the spec is .008 to .042 inches. You want about .010" with the gasket in place. A thicker #2 washer will decrease the endplay.

Once you get the best #2 washer figured out, stack the forward and direct clutches on a flat surface and set the pump into them with the correct #2 washer. You'll see a gap where the #1 washer goes. Now select the thickest #1 washer that fits into that gap without forcing the pump away from the forward clutch. That is your #1 washer.
