Who's Created/ Converted a Short 727 Using a Truck Tailhousing to a Slip Yoke?

Guys, I would really appreciate it if this thread can stay on topic. I am aware that a shorty kit can be had from A&A but that eliminates the governor which means manual shift only. I have several short transmission that just have the bolt on yokes (No parking brake drum types). Boring the tailhousing for a bushing or bearing in no problem for me. So basically what if any rework has been done to a stock output shaft? Or does this require a custom made shaft only?

Thanks,
Tom
