Belt Selection Guide for 2003-2004 Cobra

Please note that the information for this guide was obtained through 3rd party sources so use at your own risk.  There are also size overlaps with certain pulley sizes.  This Guide should be used as just that  -- a guide. 

Note:  If you are using the new Billetflow Idler Bracket you will have to add 1/2" to the belt sizes shown below for your application due to its larger size, except where the configuration already notes a Billetflow bracket. 

Note that wherever a 75" belt is recommended that the stock 75.1 belt can be used as well.

FYI -- Stock idlers are 90mm.
