Hi Reg!
Here is the telephone number for GM's Vintage Vehicle Service....
1-888-467-6853, between 8 a.m. and 5 p.m. EASTERN Time.(Posted by 'Greg' a little while ago.)
Give them a call and I'm sure they can help. In the meantime, my book shows that number as; a 1938 Chev. at 1 1/2 - 2ton.
Good Luck. sounds like a good truck.
George
