Taco 110-338 Leaks at Seal

I have an older Taco 110-338 circulator pump on my forced hot water heating system. It is leaking at the seal whenever the pump is operating, pretty steady drip and pretty obviously a seal.
Is a seal kit available for this old thing? I couldn't find one. There is a pump head available that would be used with my existing motor and it costs about $100.00 and I'd need to put it in. Doable but am I wasting my time? Is the Taco 007 series the kind of pump that is in use today to replace the 110-338? Would I be able to easily figure out how to wire it in based on how the existing pump is wired?
The leak is all that's wrong, pump still pumps but basement is getting a bit messy. Thanks for any and all advice.

That is a 3-piece pump, and there should be repair parts available, but if not, you could replace it with an 007 series. Check the flange-to-flange dimension and, of course, match the pipe size.

Check Pexsupply for the parts.

If I'm not mistaken ( and I may be, please VERIFY the part number before ordering! ) but this appears to be the seal kit for that pump:

110-275RP - Taco 110-275RP - Taco Sealer

Here is a parts list:
