Basically, I put a new input and output shaft on an NP203 gear reduction box and hooked that in front of the SM465.
In actuality, I used a Dodge NP203 input gear and put a spud shaft on it to work with the clutch. I then took the NP203 intermediate shaft and had it splined to take a slightly modified SM465 input shaft.
Overall length of it is 9 inches. 3 inches of that is adapter.
I don't currently have any pictures handy(but I do have a TON of them on my laptop which is packed away)
Project started after my frustration on not being able to find a SM465 version of the NP203. After getting the gears made, I found one(the NP203 with adapter cost me $250... no comment on the price of the gears <IMG SRC="smilies/eyemouth.gif" border="0"> ).... but continued the project ANYWAY since the gears were the most expensive part. I traded the NP203 I found and actually tracked down another one that I am holding onto for now.
This has been a 2 year project that I am finally wrapping up. With it, I net a double low of approximately 120 to 1 in my Land Cruiser.
Unfortunately, as they say, hindsight is 20/20 <IMG SRC="smilies/frown.gif" border="0"> Since starting this project, I've seen/dreamed of MANY other approaches that would have worked and SEVERAL that would have been cheaper. I still MAY use one of the other ideas floating in my mind but I still like this project <IMG SRC="smilies/smile.gif" border="0">
