Could use some guidance on mixing and matching clutch parts

So... I bought an RT4WD transmission from Dom. Not sure what year it is yet. I have been searching the archives for background info. I am pretty confused right now. My car has almost 235K on it. My plan is to purchase a SOHC ZC so I can retire the original A6, and use this transmission so I can retire the original transmission. Make sense? When I do this, I also want to replace the clutch. Maybe the starter as well.
My car is a '90, with a 212 mm flywheel and a 20 spline count, I think.
From my reading, the RT4WD used a different throwout bearing than the Civic & CRX Si.
If the transmission is a 1990 or '91 it's pretty much a no brainer. I have to get a kit for a '90-'91 wagon. Who sells a wagon specific kit?
If the transmission is from '88 or '89, what would I have to use for a flywheel, clutch and pressure plate?

and Exedy lists clutch kits for:
1988 RT4WD (210 mm, 20T): 08710
1989 RT4WD (200 mm, 20T): 08019
1990 RT4WD (210 mm, 20T): 08020
1991 RT4WD (210 mm, 20T): 08020
Not sure if the above info (diameter & spline count) is accurate from what I was reading in my search.
If I were you, I'd just go for the 1990-newer clutch setup, and upgrade the flywheel to the 212mm diameter flywheel if my car was not already equipped as such. With the 1988 transmission (21t spline) you're kind of stuck. I had Clutch Masters change the center hub portion of my clutch disc from the 20 spline to 21 spline because I thought all my transmissions were of the 1988 vartiety. In the end I had to pay them to change it back, because it turned out that I only in fact had 1 transmission with the 21 spline, and 2 with the 20 spline.
As already mentioned, you should get the throw out bearing seperately.
Count you splines carefully!
Is their a tag on the tranny that identifies the year?

What weight flywheel did you end up going with? I don't want to go too light and make it a pain in the ass to drive.
hi. You can always try your local dealer or online shops. I always get great deal online. it is just a matter of searching and comparing.
Mine is an 88 so I went through this when I replaced my clutch
clutchcityonline.com is where i got mine, pretty fair prices and fast shipping
If you have an 88-89 spec transmission with the smaller mainshaft size/spline count that would normally require the entirely smaller clutch/flywheel set-up you CAN run a much better set-up.
Use a clutch disc for a 1986 Honda Prelude/
This clutch disc is the same exact diameter friction surface as the 90-91 spec Civic clutch, but with the smaller 88-89 center/spline count.
I used to run an 88-spec ZC main/countershaft/gear set in my 1990/1991 Civic, and I used the 86 Prelude 2.0Si clutch disc with the 90-91 spec Civic pressure plate and flywheel.
