]2eDeYe Posted April 20, 2010 Report Share Posted April 20, 2010 What Datsun/Nissan RWD transmissions are the same length as a 1977 L20B 5-speed? Got a line on a hardbody 5-speed behind a Z-24. Is this the same length as the aforementioned gearbox? Same driveshaft splines? Will the diff, from the hardbody, bolt into my 1977 H190? Quote Link to comment

]2eDeYe Posted April 20, 2010 Author Report Share Posted April 20, 2010 Assume you want an L bolt pattern? Slightly longer at 33? same splines. It will if a 2wd and a 4 cyl motor. Not for an L, this is for a KA. How much longer? I'm trying for a bolt in trans behind the KA using the stock 620 crossmember and driveshaft. The hardbody has a Z24. I want to use the 5-speed and the diff to keep the speedo somewhat correct. It would be awesome if it all bolts together into the 620. Quote Link to comment
datsunaholic Posted April 20, 2010 Report Share Posted April 20, 2010 The Hardbody NAPS-Z trans most likely is a FS5W71C, which is longer than the B type used in the 620. I don't know positively what date they switched from the B to the C type trans. If you want a bolt-in, you need a 2WD longtail 720 NAPS-Z 5-speed to go with the KA. Problem is there are both short and long 720 transmissions out there. I know a '83-84 KC one would fit. Probably 82, 85 as well. Quote Link to comment
]2eDeYe Posted April 20, 2010 Author Report Share Posted April 20, 2010 Guess I'll be bringin the tape measure next time I look at that truck. That's for the help fellas :) Quote Link to comment
datzenmike Posted April 21, 2010 Report Share Posted April 21, 2010 I have it on good authority that the truck FS5W71C first used in the '86.5 Hardbody is 33" long, making it 1 1/2" longer than the stock 620 5 speed. This is the shortest of all C type 5 speeds. For the cost have the front d/s shortened as this is an excellent, rugged 5 speed and worth having. The NAPS 5 speed is a perfect fit without modifications but a bit light for a KA. Quote Link to comment
]2eDeYe Posted April 21, 2010 Author Report Share Posted April 21, 2010 $50 to shorten the shaft if that's the tranny I'm looking at. I think that is worth it in the long run. Thanks again. :cool: Quote Link to comment
]2eDeYe Posted April 25, 2010 Author Report Share Posted April 25, 2010 As a follow up... Not sure what I was on last time I looked at that truck. It was an 83 720 with a Z24. It had a B type 5 speed. It also had a 3:54 diff, both are now taking up floor space in my garage. Quote Link to comment
nis720 Posted April 25, 2010 Report Share Posted April 25, 2010 My 86' 720 came with a Z24 (carb) mated to a "B" tranny. I think I have a short tranny. Here's the overall length Quote Link to comment
datzenmike Posted April 25, 2010 Report Share Posted April 25, 2010 Excellent!!! 2wd right? Long or short wheel base? KC? Quote Link to comment
moparvwfreak Posted April 27, 2010 Report Share Posted April 27, 2010 My 86' 720 came with a Z24 (carb) mated to a "B" tranny. I think I have a short tranny. Here's the overall length i want your trans..... that would match my short tail 73 4spd right??? Quote Link to comment
datzenmike Posted April 27, 2010 Report Share Posted April 27, 2010 Only the length. This one has a Z series bell housing on it. If you can find a junk 620, 280z/zx or 810/Maxima 5 speed you swap the front case onto it. Here's a picture of one with L bell and speedo drive.... Is it from an '80 720 originally??? It now has a car cross member on it now. I have one from a 4x4 but no speedo in the tail stock. I knew these existed but have never solid proof of where/what they came off of. Quote Link to comment
moparvwfreak Posted April 27, 2010 Report Share Posted April 27, 2010 not an issue. i ahve a trashed 620 5spd that i could rip the bell off of. Quote Link to comment
