I don't think it took a long time, just the normal 3 months or so. The problem probably was you couldn't really buy them until Feb/Mar 1974 and then only existing stock, or not yet allocated vehicles off the rolling schedule . To get one before production ceased in September you'd have to order one by say June-July which meant you really had to be quick. So if you first saw one in March or April, mulled it over for a months or so, went to a dealer to buy one in June and find there was only Green 6cyl ones left unallocated so you had to order one, but the new series was out in October what would you do?
