Used GM Part #15589619 Bellhousing Inspection Plate
This is correct for 1991-93 GM P series trucks (Step Vans). But fits nicely on GM casting #15562388
(Part #15562385), hydraulic clutch release bellhousing.
This particular cover has some missing paint and very light surface rust.
This is for a one piece rear main seal, when used on a two piece rear main seal there will be a gap.
