Tranny linkage adjustment

SSG, I'm thinking internal if you've gone through all that.
Coming from any gear going to reverse it grinds the same?
Using gear lube? Last time changed? A lot of gold speckles in the old?

Shifter/linkage.... Do you have metallic as opposed to nylon bushings for the shift rods? Make sure they aren't worn and/or sloppy.
Pull the boot off so you can see the gate. Engine off, shifting out of 1st going to 2nd. Is the gate dropping all the way consistently and not bouncing through the travel?
With a helper shifting through the pattern can you see two rods trying to move at the same time?

I'm running Pennzoil synchromesh GL-4. Just changed it over the winter and the old oil was SAE 30wt. and I didn't notice any gold or metallic sparkle to it.
The linkage is all adjusted properly and has metallic bushings and are all snug.
With the engine off, I can shift through all gears with no problem or binding including reverse.
With engine running, it grinds going into reverse no matter what I do. I've tried double clutching, putting it in all other gears then going to reverse.......
One thing I noticed, If I adjust my clutch to have any space between my throwout bearing and the pressure plate levers, then I don't get enough disc departure and the car creeps in gear and is tough to get into first. Could this have something to do with the grinding?
