I needed a new timing tape for on my 340 and ended up having to buy a set covering multiple sizes. I used the 7-1/4 inch. If you can make a home for any of the others on the set, please PM your address and I'll mail it to you. I hate to throw stuff out if someone else can use it. Note: the end of the 8 inch is buggered up a bit, but the rest of it is certainly usable.
