I had some original Plymouth GTX's with 40K-55K miles in the mid to late 1990's that were working on 30 year old radiator hoses, spark plug wires, drive belts, shocks, alternator, distributor, carb, etc. If some of those hoses lasted 30 years back then, the ones from the later 1980's should have an easier time of it. The hoses on my 1999 look almost new and won't be getting replaced any time soon.
I'd replace the hoses on your Turbo-T, and save them. Those and the Grand Nationals are some of the only worthwhile Detroit collector cars to come out of the 1980's.
