Born in 1986...
According to the records I have, your machine is a 1986 model. The spin tube could be a few different varieties as I wasn't able to locate your exact model number but looking at a different Inglis produced in the same year, the Inglis PN is 20056848 which subs to Whirlpool number 383928 or 285896.
This is the shorter version for later models. Whirlpool switched from the older, long spin tube to the short one in the late 1970's I believe but Inglis continued using it several years later, well into the 1980's. So, I'd measure it and confirm if its the short version or long version before ordering. Short version is somewhere around 13" and long is 18.5" I believe. Both were common parts so you should still find whichever one you need around.
As for outer tub, you'd either have to find a donor machine or restore the one you have if it is salvageable. Chances are slim to none you'd find a new one of those sitting on part shelf somewhere.
Maybe take some picture of your outer tub and post them. Some of the experts here might be able to give you an opinion if its salvageable or not.
Good luck and keep us updated on your progress
