PK Ripper year?

[furry]

Just wanted to find out what year my mates loop tail Ripper is.  The frame number is PK65179, any info would be appreciated.

Is there a referance site for this stuff?

Thanks in advance,

You really need to post a pic. Serial #'s don't work for PK's I'm pretty sure. A pic or descripition will clear it up. The rear triangles are different for certain years. I think looptails finished around 82-83. Mine was around 82.
