You should have one.

Ebay. I found mine on ebay.

One that will fit 351 C or W, 302 and 289 should work.

Goes between the block and the flywheel during assembly.

With the engine on the hoist without the flywheel installed, put the cover on so the starter hole is on the correct side ( right ). The positioning studs will hold it in place until you bolt the flywheel on. Do the clutch and then bellhousing. There will be anywhere from one to four 1/4 x 20 bolts that hold the cover to the bellhousing.

That should do it.
