You're in for a load of fun... I replaced my rag joint a while ago with the HELP thing... the only thing from the kit you'll be able to use is the actual joint and shims, you'll need to buy a 4 nut-bolt-washers set for each joint and discard the threaded dowels that come with the kit. I thought I had a post with pics but it seems I removed them... Seems you actually posted there 2 weeks ago, to answer your question, yes, you pretty much tear the thing apart, drill out the rivets and end up only with the shaft in 2 pieces, or 3 if you remove both joints. I'll see if I can find the pics and re-post them.
On other topic, where's Surprise AZ?
EDIT: No luck with the pics at my job's computer, will look for them when at home this evening.... (in case you are wondering why I don't just take new pics, I sold that truck 6 moths ago...)
