you sure? that is a 1980 part number and I would think the old carb turbo oil return would be different than the 83-86 turbo drain. yes it is a discontinued item. is this on a 2.3L motor or for a inline six swap? if it is for a 2.3T might wanna try over on turboford.org for the drain on my turbo setup (might have mock up pics this weekend) I am using a bolt on pipe thread adaptor available just about anywhere or made at home easily, some -10 line and a bung welded in the pan. low dollar (got all the fittings for free in a plumbing grab bag, the -10 hose came on an oil cooler I got on ebay that I resold for profit while keeping the hoses and the adaptor was $14.
