There are a few set's of afr's floating around for sale.. just seen some bare 210's for sale as a matter of fact.. You can't really have a timeline w/ these project's due to the rarity of the part's we use.. Plan accordingly and it should work out.. Granted it took me 3 month's to get my heads.. which id on't consider that bad w/ afr's lead time goin upto 6 month's..
