Mitsubishi Forum - Mitsubishi Enthusiast Forums - I need help finding o-rings, 97 montero ls

First time post.

I know this is a issue that has been covered several times.. and I have read about 30+ threads on various fourms.. so before you tell me to use the search button! I already have:)

in short, I took a job that pays a lot less so that I could stay in Tucson Az. most people think, why? and I tell them this is out door and 4x4 heaven. that being said I could no longer afford my 35k truck so I sold it and bought a 97 montero for not much money. it needs lots of work done to it and it has 155k miles but.. Im debt free :) and it does run straight down the road.

I have ordered several times and got the wrong parts from napa, oreileys and rockauto.com so im asking you where can i get the correct part. the rear cam o-rings are leaking pretty bad. I keep ordering the parts but I keep getting what look like front cam seals rather than rear cam o rings. I have read many threads on this topic and everyone says just go to the dealer and get the part.... only there is no dealer here in tucson. nearest one is a 4 hour round trip.. and with phoenix traffic it might be more like 5.

last weekend I pulled the rear cam cover off, Opened the little box with the new seal in it only to discover that it was the wrong part. so I put the old one back in with a little (really little amount) of high temp rv seal. which has stoped the leaking on that side for now but the other is still a problem.

1) I am confused about which engine I have. 6g72? or 6g74? and what is the difference? I have a 97 montero ls with a 3.5l engine. maybe its not a 72 or a 74. just wanting to make sure I have the right engine.

2)where can I get the rear cam o rings for a 97 montero ls? I know I should get them from the dealer blah blah blah.. but is there a reliable website where I can order them and get them faster?

I have so much work to do on this thing but first on my list is stop all the leaks. and I really really thank you for your time and responces.
