Not too hard of a job but I would recommend you find a new housing. Pulling the distributor and fuel pump is like any other V8 out there. You probably can install the entire assembly with everything attached but I take off the distributor and fuel pump the clear the area out. You’ll want to replace the cam belt while you are in there unless it was recently replaced. Jerry Woodland sells oil pump rebuild kits if you are so inclined. If you pressure is good I would probably pass. I carry a spare housing in my car for long trips so buying a spare is pretty common in our community. Most of us wing it when it comes to tensioning the belt, not too tight but not too loose. Make sure all the marks are lined up per the manual and you should be good to go.
