Here’s the part number and bill of materials from opposed forces.
http://opposedforces.com/parts/legacy/e ... tration_2/The part number is 10105AA790
If we google that, they’re readily available, thus search for eg genuine at lowest price best convenience and or vendor reputation.

But caveat emptor, do your own research, eg gates make 2 levels of (EJ) timing kits, make sure you get the better, slightly pricier version.
Where to buy? Search for a local ajusa dealer (or get your mechanic to order).
Or go online. Local vendors for oem can be competitively priced, eg BCW, GIR, carmods etc.
