got a question for all you guru's. Why is everyone doing conversions with a sm465 or a sm420 and the toyota transfer case? On my cruiser the option I took was a 465 and a dana 18. I studied everything and felt the advantages of a dana 18 far out weighed the advantages of the stock t-case. With the 18 you have twin sticks, already mounted on a case bracket on the t-case, so you dont have to cobble or build linkage. You also have the option, that i took, just plug in a warn or saturn overdrive. If you want to keep your rear drum parking brake, thats no problem either cause the majority of the 18's had the parking brake. Theres alot of modification to use the stock t-case especially using a sm420. I was just curious, is there some advantages I have missed, or something im confused about. Let me know.
