Another 5 spd transmission swap question

[MEZZZ]

Well, I've been away for awhile, havent worked on my car since last fall. Work, family, life allowing little time for awhile now.
I am getting ready to get back to work and I am interested in doing a 5 spd swap. I have been searching local Craigslist ads and found an '81 with a blown head gasket and rust. Told the tranny was great when parked. I beleive this would work.

I also found an '86 300zx non-turbo with 77K on it that they are parting out due to it being wrecked. Ive tried to search on this, is this a tranny that would work?
Thanks in advance

The short answer is no because of the level of difficulty. It's been done but it does require some machine work and fabrication. You can use a 5W71C transmission with a 280z-280zx front case to fit the transmission to your L24/26/28. It would require some grinding to clear the front gears on the input and counter shafts and swapping the front counter shaft bearings. Also you'd need to put the 280Z/280ZX front case in a mill and drill out the 5th/reverse shift rod hole to 16mm from 14mm. You'd need to make a trans mount and a longer driveshaft since this trans is 2-3 inches shorter. Lots of work while the 280ZX trans is essentially a bolt in.
