James, we will consume all your inventory of older revision of timing covers. The new revision is not approved yet (in quality being measured). We also have to make sure that older revision pulleys from another supplier are all used up before timing cover new revision can be used. Chances are that we may need to order more older timing covers from you to make sure that the timing cover changes happen after the pulley changes. The new timing covers do not work with old pulleys. Hence we need to monitor this closely. Make sense?
Your numbers below 1+2 do not add up to total inventory. Please double check
