tbbahner 27 #1 Posted March 5, 2010 Can someone give me the width/length for a drive belt for 79 C161 Auto. Manual lists 2 belts for single cyl., 7473 and 7478. I believe the 7478 is for the 8sod, My parts guy crossed over the number and I got the wrong belt. Seems like I have a heck of a time getting the right belt for these guys. Don't the the one for the twin but if someone has it, I'll log it down too. Thanks for any help Tom B Share this post Link to post Share on other sites
