Scott,


I wish I could be more helpful. I assure you these parts are not reproduction and have been together for a long time. They were covered with grease, grime, and dirt before being carefully cleaned.  I added the bolts since they were missing. This came to me along with a vintage cast iron M/T scattershield of a similar design. There was also a later hydro formed lakewood shield with the parts. I believe the racer was constantly upgrading to the latest and greatest which is why this bellhousing is not damaged. It was simply removed to be replaced with the latest on the market. I did not know they reproduced this bellhousing. That must have been quite  a task since this is a very heavy piece and likely tough and expensive to cast.

Thanks,

Jason
