First time I looked, I didn't see how it came apart either
I pulled my rack apart (2 actually) last week.. It can be stripped down to every last part. I scored new pinion roller bearings, the pinion ball-races were still like new. The rack bushes don't appear to wear at all. I recommend you service your rack while it out and we are here.
When I fitted my 7.5" wheels I simply pinned the rack to have stops that hit the outer ends of the opening of the housing. Rubbing wheels on full lock is a no-no, As is asymmetric steering...
Now I have screw stops to get a minimum turning-circle after I dial in my wheel alignment. I didn't take any pics but I still have 1 fully disassembled rack that I could do a how-to if anyone is interested? The modified rack in the pics may be for sale (RHD). I'll show a pic of the stops tommorrow.
The second hardest part is removing the ring-clip at the end of the housing.
