[V8] Serpentine belt sizes...

[toml99 at todomundo.com]

Hey, well the only thing the 5-speed needed was a serpentine belt.   
It didn't look bad, but started "chirping" the day I went to pick up  
the car.  I went to replace it today(I had a fresh belt for the '90  
3.6 that was going in when I do the timing  
belt.....someday.....Noticed the belt that was on the 5-speed was a  
Conti 2433, and that my replacement belt was a 2460...(4.2 has the  
2480).  Just wondering if anyone knows why there are both the  
2433/2460 spec'd for the 90-91?....Belt fits and chirping is gone,  
but wondering if for some reason the 2433 may have been for the 5- 
speed?  The chirp came from where the label was printed, belt was  
just a hair wider and was noticeable when running(shiny spot on side  
of belt there)....Threw it in the trunk as backup....Also curious if  
there was ever a manual (addendum) related to the 5-speed/tranny/ 
clutch as it would be nice to have if it ever existed.....Sunny and  
beautiful here...Sincerely Tom
