Can anyone tell me what a Gatorback 080805 measures
in length?
My 797 belt was 80 1/8" and my 810 was 81 5/8". So
what is a 805?

Gates belt numbers have the size listed in the last 3 numbers of the part number in my experience. Example is a stock belt K080751 which 75.1 inch.

Gatorbacks are numbered the same BTW.
Your 797 should have been a 79.75 inch belt

The measurements I quoted up top here, were taken right off the
box cover. I have a Napa 080810 and it works but I need one
size smaller.

Should be 80 1/2". What pulley set up are you running?


I'm running :
2.93 BF upper pulley
4# lower Metco set up
BF newer snub idler
3-100 and 1-92 BF idlers
3.2 alternator pulley by Metco
The lower idler is in the bottom position
Napa belt: 080810, length is 81 5/8 "

my belt tension shows that the belt is a bit loose,
I ordered a 080805 Gatorback

That may or may not be true, but I think the packaging is going to say 75-5/8" for a Gates K080751

That is incorrect!

K080751=75 5/8"
K080755=76"
K080760-76 1/2"
K080774=77 5/8"
K080780=78 5/8"
K080785=79"
K080797=80 1/4"
K080806=81 1/8"

This link may be one of the most resourceful web pages for 03/04 Cobras that ever existed. Props to Cobra Bob for hooking us all up.

The first number represents that it's a Poly V belt, 2nd and 3rd is the number of ribs, 4th, 5ht and 6th is the length in inches and the last is the length in 1/10's of an inch. So 4080805 would be 4=poly v-belt, 08=8 rib set up, 080=80" and 5=5/10" or 1/2". Pretty easy really. If you check the link I provided, Bob gives you exact belt lengths for numerous set ups. You may be able to find your exact set up in there and make easy work of this.

I looked around and you are right. All I could reference was the 751. What's your source on the other measurements? I don't see a pattern on the differences in size
