Help!!!!

[GMCFamilyTree]

Gents,

I have a 70 I6 3 on the tree standard and in this cold weather put too much M.A.N. on the column shifter and sheared it. I've retrieved all parts but the guys at LMC and Brothers told me I cant get the part new. Brothers told me to check the forums, there are some of you out there that repair them. I'm stranded in the front yard looking for a shifter and looking for some help/advice. Also any advice to loosen up the gears in the cold weather? Thanks!
