HotCams makes shim kits but i found they dont carry the larg sizes. Honda dealer local to me had all but 1 shim i needed and all were like aprox $5 each as compared to toyota pricing of $8+ (canadian) im not sure what the toyota shims are but i remember people saying they are arround 10 bux each.
So simply raid your local pick a part for your normal range of shims and order any thicker ones you might need.
