Jobo make or rather made 5x4 spirals that fitted the 2000 & 2300 series of drums, others as well. They are sometimes available on ebay. I got my 2nd drum and spirals by posting a wanted advert on this site. Each spiral holds 6 sheets of 5x4 and 2 spirals fit in each of my 2000 series tanks using 2 litres of dev with inversion agitation

4x5 I'm assuming. 2509N is the current reel which fits the 2521 and bigger drums.
The 2840 is a print drum. It can be converted to a film drum but by the time you buy the centre column and funnel you'll have spent the price of a used film drum. If you're doing larger sheet film then the print drum works.

Assuming your 2840 drum is the same as mine, that is, it is a two piece drum, then you can use the bottom part of the drum for rotary processing 4x5 film as I do.
You will need a 2509 reel (I have this) or a later 2509N reel (it has clips making film slippage a thing of the past, I'm told)
I cannot remember the length of the centre core for the 2840 drum but if there is a centre core that fits inside the bottom part of the drum that is the one. The centre core from the 1520 drum is the same size and same thing!
The bottom part of the 2840 drum is also sold as a film test drum for 4x5 film. Why that name was used is a mystery to me, but that was the original name it was given in the first brochure I have for the 2800 series of drums.
I develop 4 sheets of 4x5 at a time using rotary processing, works a treat.

Ya the bottom part of the 2840 is same size of the 2521. It's called a test drum because you use it for test strips. It's not a test film drum. I can't remember if the test drum has the paper ridges or not. The 2521 won't.

The clips on the 2509N are also designed to break up and randomize the developer flow during rotation, not just hold the film more securely. I quit using the Jobo for 4x5 because the original 2509 reels caused strong flow mark patterns with my chosen film and developer and the slow rotation speed originally recommended with film in the CPE2.

What's the best Jobo setup to process 8 X 10 C41? That's all I'd be using it for as I can't find anyone locally (Tulsa, OK) to process.

Best? An Expert drum with a big enough processor.

CPA2 or CPP2 with a 3005 Expert drum - the 3005 is specifically designed to handle 5 sheets of 8x10 at a time. The CPA or CPP are required for using Expert drums - the CPE can't take a lift that will engage the drive cogs. The CPA has 1 degree accuracy in its thermostat. The CPP has .1 degree accuracy, and also has a cold-water solenoid valve. If a CPP is in your budget, it is the best tool for the home darkroom. If you cannot afford a CPP, a CPA will do.

Unfortunately Jobo has discontinued all but the ATL line
The ATL will work well, but is very costly
You'll have to find a good used CPP (or CPE) on that auction site. Watch the shipping. I purchased a second good used CPP last year for backup parts when I heard Jobo was considering discontinuing....the seller packed in huge oversize box with tons of styro beans and tried to get me to pay $180.00 shipping. Reasonable shipping is tighter box with beanies, running around $45.00. (including lift). UPS rates are by dimensions, and go up quickly if oversize.
