So am I missing something? Today I replaced my upper with a BF 2.93. Along with that I also installed a 90mm ford idler pulley. When I got the 2.93 I also got a gates 74.5" belt. When I installed everything I tried putting my new belt on but it was too short. So I reinstalled my old belt. It fit perfect. I checked for any part numbers on the belt and found out it was a gates belt too but the the last 3 digits if the part number were 797 which indicated that its 79.7 inches. Now why would I have that if stock is supposed to be 75.1"? I don't get it.. I've been driving around and haven't had any problems with it. Nothing at all. I've even taken the cobra out on some stang cruises and its never given me problems. Now I'm kinda suspecting it has a lower. Idk. I hope not because I've been driving the cobra around jus thinking it's stock. What do you guys think? Does any one here have only a lower? Btw what does the stock lower look like anyway?
