Since I have only laid eyes on my paragon transmission are there differences between the years of the same model? Mainly, would any Paragon PV33L have the same dimensions as my PV33L?

I have seen a few PV33 transmissions for sale that have don't appear to have a raw water cooling system on the vdrive portion.

You can see the difference below. One appears to be internally cooled. Mine is raw water cooled.

This is more just curiosity while I plan out this off season.
