I am 99% sure that is a NP 205 shifter the large hole is a shouldered bolt and the small hole is for the shifter rod... I am pretty sure the np205 shifter is the one you are looking for..
Master Yota is still here now and again. Its winter up in his part of the world and he may not being doing much truck stuff right now. When he looks at this, he may be able to tell you what the lever was from, if not M37 as he did a power swap into his M37CDN which is documented elsewhere on this site.
I received a reply from a pm I sent to Master Yota and he says the shifter is from a chevy, ford, IH truck and maybe divorced...But thats not logical to me as it has a large pivot like the married to sm465 ones I have, it seems to me it would be a long rod type if it were from a divorced transfer case..
Ill keep looking on ebay and such for this type of shifter..
