You can. But be aware that the splines on the tailshaft change in 75, so if your donor trans is earlier, you may have to swap the planetary and rear drum parts.
When I bought my 70 industrial 413 (rebuilt it as a budget rebuild with my son), I also got the transmission too. The transmission has one of those brake drums for the parking brake that I'm hoping to swap out with a regular tail shaft and housing. I'm hoping the transmission has the HD stuff!
