m47 swap ?

[dieselbrick]

I've managed to finally find an m47 to throw on my 82. I know that they came stock with the m46 because of the stronger casing, but I really wanted the actual fifth gear. I've opened it up and everything seems to be in very good condition. I'm not planning on throwing any crazy power at this car because it is my daily (maybe a turbo at some point the lack of power is a bit annoying). But I was wondering if anyone with more knowledge on d24s would see any issue with putting the m47 on there.
I'm already planning on having the front driveshaft shortened by a driveline shop, I don't know if theres any differences between the gas m47 driveshaft and the diesel one but I can't get my hands on either.
