Thanks, I think the lead spacing is too small on those. The cap its replacing is also much larger and wasn't sure how to know what ripple current to look for or if it mattered.

typically these large low value caps are used to tune the horizontal sizing a bit. (without seeing the schematic i'm not 100% on that tho)
but, 10uf is close enough to 6.8 that your width will still be adjustable enough to compensate for the difference. Don't forget that electrolytic caps have a rather wide range (20%) of acceptable value for it to be, to be considered "in specification"
as far as caps go... i honestly don't know the difference between a tiny fart can sized 4.7 uf 50v Bi-polar cap that I usually see at the parts places and online and the huge 4.7uf 50v bi-polar cap that (other) monitor chassis use for width sizing. I got a fair stock of the proper big ones, so i'm not really worried about it...yet... but i'll be damned if i know what the actual difference is or if the little bi-polar caps can be used in exchange.

yeah i am out of my depth with spec'ing this last cap and it seems to be pretty important so I was trying to find a replacement someone had used prior. So far no luck. May go with the 10uf if I don't find anything.

So I started testing some of the caps I am going to be putting in and am wondering if they are good. Below is a picture of a 100uf 25v cap hooked up. The table says it needs to be less than .32 but the screen says its good as long as its lower than 200uf. Not sure what to trust....
EDIT: I am not trusting the caps, so I just rebuilt a full list on digikey for the chassis and ordered all 56....if it all works fine I will publish my digikey list.
