i just used a shorter belt, i think a 730 was the measurement

part # 770k6 to keep the ac,ps and delete the smog(this belt keeps the stock routing)

I got mine at auto zone

No...mine were a pain in the *** too. I used the "bolt as a tap" method. I saturated the threads of each hole with carb cleaner and used the correct thread size bolt to clean the threads of carbon kind of like a tap. It went like so...spray the threads with carb cleaner, turn the bolt in one thread, back it out, clean the carbon off the bolt, spray the hole again, screw the bolt in one more thread, back it out, clean the bolt with carb cleaner, spray the hole with carb cleaner, put the bolt back in the hole and thread it in one more thread...and on...and on...until the bolt threads all the way in up to the head. Took me a good hour each side.

You got lucky, I couldn't even start mine in the threads. [:@]

if you are running ud's i think the belt is 747k6 for ud's and770k6 for stock.

i was just told by my buddy (hes a total mustang head) that my belt is too long, by about 1/2" to an inch..i have a/c delete and smog delete, with just the delete pulleys in the respecful spots..i also have underdrive pulleys..i have the stock belt size on now, and its too big

so will the 747k6 be what i need? on autozones website it says "Application: Without A/C"

its much easier just to swap on heads that are not smog legal
