billetflow/amazon hubs/rings - not interchangeable

[P49Y-CY]

this is information that's probably about 10 years old in the terminator world, but in my searches this was the only thread i could find with this specific question:

http://www.svtperformance.com/forums/showthread.php?680753-Billetflow-Pulley-on-Amazon-Hub

i have a 2.80 amazon pulley/hub on my vert and a 2.93 billetflow on my coupe. i also have a 3.65 (stock) billetflow ring in case i ever need to de-tune for california smog and recently tried to use it on my vert.

even though they look identical, the bolt circle spacing is just a hair off and they do not bolt up.

fwiw :beer:

yeah they make (or made) several different sized rings... 2.76, 2.93, 3.10, 3.40, and 3.65. as long as you have one of their hubs, they are all interchangeable.

but they will not fit on an amazon hub.
