Those running a dual setup and find this problem need to make sure to buy whats known as a match pair of belts. They're cut from the same batch of rubber and thus, are exactly the same size. This is very common for applications like transports that use dual belts, but not so much on these cars so expect that they may need to be ordered in.

Good to know....My Merkur XR4Ti had a dual belt setup from the factory and finding two belts that were the same length and would both tighten up correctly was a pain in the ass :cuss:

You'll see why once you reinstall the air pump. The belt going to it will ride on the "other" side of the water pump pulley as opposed to the alternator belt.

GuitarJunkie28 used to sell serpentine conversion kits for our cars. There may be a few sets in circulation, but they haven't been made ever since he passed away.

And yeah, NAPA part 3L220 is the "yoohoo" belt.

Glimer drive kit for an FC.

$300+

No offense to Gilmer, but are those really that expensive to make? Seems like they have a monopoly. :D

$316 for 3 aftermarket pulleys and a belt isnt that bad most underdrive pulley kits are the same or more. I paid for $200 for one pulley on my Z.

On the subject of the Dual belts.. both the same.. and the one smaller one...

Racers have been doing both for a long time. Some go with a short belt.. some with two long ones.

I personally dont like the PITA of putting on a smaller belt, so I always went with the longer belts.

HOWEVER

High RPM with a stock belt, on a ported 10K+ motor=belt flying off.

SO I always get my belts from the local store, but in a wider width. I think the stock is like 12MM or something. 15? I cant remember, but I ask for the stock belt, and get the number and then up-size on the width.
I believe its a 17MM wide belt.

NOW. with dual belts.. One will be slightly longer. Realistically its almost impossible to get the exact length.

SO what I do then is put them on, TIGHT.
Drive the car around town a little.. put a half hour on it.
Then open the hood, blow off all the dust from the belts seating, and then re-tighten a little.
About 3 or 4 days later, blow the dust off, and then check tightness.
The belts will wear a lot in the first week, as they seat in the groove.

After that they will last for YEARS of high RPM abuse.

(I need to get a sig configured, and my avatard)

But are those under drive pulleys or stock size?

If they are under drive pulleys that might be a hella steal.

I heart you sir.

I am buying one of these today. I hope they have one in stock.

Bought one. I am gonna put it on and try to get some pics. If it turns out to be really hard then I'll do a write up on it.

It's pretty simple and straight forward, but a write up is never bad. :D
