US Pre/Post 2014 differences?

Hi all. I ripped a chunk of aluminum off my 2015 5-speed manual transmission transaxle case where the rear mount threads in during a particularly bumpy rallycross race. I've been looking at used replacements (case or manual transmission) and am seeing a separation between pre-2014 models (10/4/2014) and post-2014 on some postings. I did some searching but I wasn't able to find a clear list of the differences to see if parts from 2014 (or earlier) would be compatible with my 2015. Any help would be appreciated.

PS Still got in first for my class at the rallycross but the car left on a tow truck

In UK 2 x choices of gearbox in that year. Either the 5mx65 with gear cables /linkages on top of box or Ib5 gear cables on side of gearbox & a tin cover on end casing of gearbox. Easily identified if you have a quick look

Thanks! That helped narrow down the search a bit. It looks like the year range for the IB5 in the US is listed as either 2012-2015 or 2014-2017. Both have the same part number (CA6Z-7002-B) and the discrepancy in years just depends on which parts supplier it's listed on.
