Dear Halley;
The main case & gears are. However; the shifting arms & tail shaft/housings vary.
If the total lenght is okay, just use your sideplate and your A-Okay.
When a floor shift (conversion) is used the arms are reversed. This is not a good idea as they often slip making it hard to change gears. If your on the column now, that's the best place.
Good luck.
