Lakewood scattershield stuff

[jbtech]

Please help me identify what I have here and what year(s) these were produced.

I have a block plate with 1570 part number and a bellhousing that I don't want to drill to line the holes up with the block plate. I could not find a part number on the bellhousing but it was clearly painted so I can start scraping away with your guidance.

I'm considering keeping the blockplate and finding the correct bellhousing. Do any of you know the matching part number I would need?
I can't find anything in the 1978 Lakewood catalog on either part. Thanks
