ok, here is the info i have gathered up so far.
over the counter parts, es2234r is your drivers side tre
es2027l is your high angle tre to your pitman arm
ruffstuff parts, tk234 es2233L and r1768
the passenger tre has a tapered hole in it. you will have to specify when you order whether you have otk or utk steering setup, that part number is es2233l they have them reamed to fit their tk234 tre and is also reamed and set for the cure to be added to the tre, the ruffstuff tk234 will not fit the serious offroad reamed es2233L it is too loose, i dont know what frank used for a tre there and i could never find anything that fit it correctly. also the parts store ES2234R looks like it will work in place of the tk234 but i wanted to buy theirs as i know they are machined to fit each other, but may be a good replacement later down the road.
now i believe you could buy the es2233L from a parts store and ream the taper yourself to fit the es2234R but i didnt want to go that route, but may in a future build. so in theory all 4 tres can be bought at the parts store, if you have the tapered reamer in your toolbox and are comfortable doing so.
hope that helps and didnt add anymore confusion to your problems. i ordered my parts from ruffstuff thursday evening they were here (maine) yesterday, they are pleasant to deal with and easilly answered the questions i had.
i will not get a chance to swap out my parts tonight, but will post on here when i am done to confirm it all works, hopefully this weekend,
good luck and let me know if you have more questions
