No. Your '85 has a two-piece rear main seal, and the '88 has a one-piece rear main seal. The flywheel mounting changed with the change in the seal type.
You need an '86-'92 f-body V8 flywheel. Doesn't matter that the factory only put them behind 305's, it'll mount and work just fine on a 350. Just ask for an '88 manual transmission flywheel.
