Guide Bar Fitment for XL12 - UT 10445C

[Smithtr]

Hi! Smithtr here. I am totally new to the HOH group.  But, I have been a faithful Homelite chainsaw user since 1981.  In 1981, I bought a brand new XL12, UT# 10445C. I still have it, and it runs great. I just replaced all of the manual oiler parts.  I replaced the guide bar once before a long time ago. I don't remember where I bought it.  But, I would like to buy new or NOS Homelite 16" sprocket nose guide bar like it has on it. These are the only distinguishable numbers on it. I don't know how to interpret these numbers. I found a NOS 16" sprocket nose bar on eBay that looks like mine, but I don't if it will work.  The part number of the bar on eBay is PT-16321-G6. Can anyone help me interpret these number on my guide bar, and tell me how to determine which ones on eBay will work for me? 
Thank you ahead of time for any information you can give me!!

Unfortunately, the bar number you mentioned from eBay is not for the XL-12. It's .325 pitch and fits smaller saws.

You're looking for PT-16381-G5 which is a Power Tip bar or SP-16381-H5 which is a replaceable sprocket tip. Looks like your current bar is the Power Tip which was very common. The 16 on your bar is 16", 38 means 3/8" pitch and G5 denotes the mount type and tip type.

They're getting tougher to find. Most guys go with an aftermarket bar now like an Oregon. There are some cheaper options as well.

Thank you so much for the reply! I know now what to look for, and what doesn’t work.
Greatly appreciated!

Hey blythkd! I have searched and searched, but I haven't been able to find an PT-16381-G5 or SP-16381-H5 guide bar for my XL12. Can you give me any clues to how to cross reference these part numbers to an aftermarket bar like an Oregon? You also said that there are some cheaper options as well. Can you expound on that a little.
Thank you for any help you can give me!

Here's an Oregon bar from Frawley's:

For some cheaper options there is Lil Red Barn, this link is for a bar and chain combo:

You could also look up an Archer bar on Amazon.

Some other members probably know of some other options.

Thank you very much! I think this Oregon replacement will work great! Can't wait to get one and try it out.
Thanks again!
