I'm going to attempt to help you learn how to recognize a poorly re-stamped starter or even a re-stamped alternator. These are round (as in cylindrical) shaped parts. GM developed roll type stamping devices to stamp these parts. It is extremely difficult to repeat this operation by hand with singular letter and number stamps and it not be totally apparent, even to an amateur. Once you know what to look for!
First GM used what is called gang stamping. That kept each number or letter perfectly inline and at the precise angle it should be. They used specific style & size fonts on certain parts. The experts here on this forum know them and can quickly identify a forged or re stamped part. Just for the record, study how straight the stamping is, or if the font changes, or if the spacing fluctuates at any given point on the part you are examining. Also GM gang style stamping usually resulted in all of the information starting and ending in the exact amount of space on the top and bottom line. I recommend you just go on eBay and look at what guys that are asking big prices for rare parts are selling. Lots of them are so obvious that they have been modified.
However, some part re-builders have finally come clean and admitted that as part of their product services, they will custom build and re-stamp a specific part & date code to your needs. This keeps them in the clear of not misrepresenting their services. I've saw them, while their products look god and operate as they should, their re-stamping is way different from the OEM.
If you dads original RA III engine is missing, I would not even worry about correct part or date codes. Build it with the best parts you can get and enjoy the car. Plenty of guys here to help you with any questions you might have. Good Luck to you.
