Re: stock drive belt size?
The accessories are in the exact same place on the 88 as they are on the 89, but the 88's used a longer belt that was routed different. I ran an 88 belt on my 89 for a while and it worked fine, just had to route it differently. Luckily I had an 88 upper fan mount sitting in the garage with that sticker that shows the belt routing.
