How to assemble TC Kline/Koni rear shock?

Hey all, having a bit of trouble trying to figure out how to assemble these rear shocks. They came with a bunch of different washers and spools. I have tried reaching out to TCK, but haven't heard back and I'm getting too antsy. How do you assemble these things?

Here's what I've got:

- (2) Nuts - 1 for the top, 1 for the bottom, easy enough

- (1) Lock Washer - for the top nut

- (2) large washers, 1 black composite(?), 1 steel

- (1) 1" spool

- (1) dust cap/cover
