Yes, me too. These guys do nothing but drivetrain stuff. Mshar is a
company in Harrisburg, PA - they do it all.
I bent the driveshaft in my 1980 full size Blazer years ago (on a US
Army tank trail). There were about 50 different driveshafts for a 1980
Blazer which made finding a used one quite difficult.
I went to Mshar at 8am on a Saturday. I asked what day I could pick it
up, they said 'come back in 2 hours'. They cut the ends off my old one
and welded them on a new tube and balanced it. All for about $100.
