Is this the ring gear info you found-
 Probably the best damper prices - https://bpi.ebasicpower.com/search_2/show.php?q=damper&qid=43469&tr=%20Damper_Ford%20Drive%20Damper Or you can save a few bucks and cut it down your self to match your old one or the one above https://bpi.ebasicpower.com/search_2/show.php?q=damper&qid=43472&tr=%20Damper_Velvet%20Drive%20Damper

Thank You, Ordered the seals today, now for the ring gear I did find information in the archives that it is a 157 tooth and the damper is either a PCM oem part or a Sach's made in Germany . I noticed when I pulled the started for the numbers some teeth were chewed up . If I am going to pull the drive I might as well replace any possible future failures. I will also replace the velvet drives front seat . Joe

Hi Joe I think that you'd have a 1 piece rear main seal since the block was cast on March 31, 1984. Also the casting code really ends in BA22, not 8A22. Those 8's and B's are tricky  The PCM part number is R047041A for the 1 piece RR seal and it's around 95 bucks at Discount Inbd Marine. Alex's Parts sells a one piece RR main seal for about 28 bucks plus shipping. Alex's part number is CS-45920R. If I found the one I think you're looking at on EBAY it's probably the same seal from the same supplier with a slightly different number CS-4592RV given to it by the outfit selling it. People have used the Alex's seal with good luck since somebody first brought it up on the forum ( it was shierh or mmasariu I think) Good luck |

There should be a date code cast into the block along with the block ID.
83 was the year they transitioned from the 2 pc to the 1 pc seal. If the date code is July 10th or earlier, it would be a 2 piece seal If it was July 11th or later, it would be a 1 piece seal An example of the number would be something like 3G11 3 for 1983 G for July and 11 for the day of the month. So if the letter after the 3 comes before G it's a 2 piece (example 3D) If the letter after the 3 comes after G it's a 1 piece (example 3J) If the letter is G then you have to look at the number after the G. Since you know where the block ID is stamped and it's upside down, if you look at that number, right above it you'll find the casting date also upside down with all the numbers buried in paint and maybe some rust and grime too.. The numbers are about as easy to find and read as the dead sea scrolls Here are some numbers I took from an engine I just looked at E4AE-6015-FA-13 6H16 The E4AE says it was a block first used in 1984 and the 6H16 says it was cast on August 16, 1986. Just as clear as mud huh? If you can get all the numbers, post them here for some deciphering help. It might be easier to pull the transmission  Here's a picture borrowed from the internet, note that the block is upside down and you can read the numbers 8C10 tells you it was cast on March10, 1988  |

I have a 1983 351w in my 85 2001 the block id is E3AE- which is a 1983 block but it does not have a date code just a tag that's says Commander Marine CM9111. My question is what rear main seal does it have 1 piece or 2 ? without pulling the velvet drive . Thank You
