Jerry, I also got my rubber parts and many, many other parts from Classic Parts for my 59.
Good prices and good service and I can't afford to buy much from the Steele guys.
I just got the truck on the road last Sept and so far no problems except the door weatherstrip is CRAP. I bought new door weatherstrip from Steele for about $100 vs. $25 from Classic but there is no comparison, The Steele product is very high quality. The other stuff went to the trash can. As they say, you get what you pay for!
