zippyg Posted May 23, 2015 Share Posted May 23, 2015 I am doing a transmission swap on my 75 280z, the 5 speed I am putting in i think is a FS5C71B but am not sure, it came with the car. The 5 speed did not come with bolts and it is obviously a thicker bell housing. In every trans swap post I've read no one has said what size bolts go with the 5 speed. Where can I find the length for the manual bolts? Quote Link to comment Share on other sites More sharing options...
tamo3 Posted May 23, 2015 Share Posted May 23, 2015 You can use same bolt from original 4 speed tranny. Quote Link to comment Share on other sites More sharing options...
NewZed Posted May 23, 2015 Share Posted May 23, 2015 Are you swapping 5 speed for 4 speed, or 5 speed for automatic? The manual transmissions are almost identical. Don't know about automatics. The local Nissan dealer might be able to get them. http://www.carpartsmanual.com/datsuns30/DatsunFairladyZIndex/PowerTrain/TransmissionCase/5Speed/tabid/1702/Default.aspx http://www.courtesyparts.com/bolt-p-234686.html http://www.courtesyparts.com/bolt-p-234688.html Quote Link to comment Share on other sites More sharing options...
NewZed Posted May 23, 2015 Share Posted May 23, 2015 Looks like automatic uses a different bolt. http://www.carpartsmanual.com/datsuns30/DatsunZIndex/PowerTrain/TransmissionCase/Automatic/FromApr-71/tabid/1705/Default.aspx He probably has the swap done already...

zippyg Posted May 24, 2015 Author Share Posted May 24, 2015 Thank you for the info guys and yes it is an auto to a 5 speed. I am celebrating the holidays and have not done the swap but I'll go thru the links provided as soon as the weekend is done Quote Link to comment Share on other sites More sharing options...
z240 Posted May 25, 2015 Share Posted May 25, 2015 You can determine the length you need by measuring the thickness of the bellhousing, plus the thin plate between the trans and engine block, + a lock washer (call it 3mm) and then adding 2 x the bold diameter or 20mm for the length that threads into the block. The bolts are M10 x 1.5mm pitch BTW. Quote Link to comment Share on other sites More sharing options...
zippyg Posted May 27, 2015 Author Share Posted May 27, 2015 Again thanks everyone I did managed to get the right bolts for the bell housing. As far as the carpartsmanual site, it is a good resource although is there any other bolt inventories that might give what the actual bolt is. I know i also need clutch cap bolts which i know is part # 30223-e4100 and flywheel bolts which are # 12315-u6000. I went to a Nissan dealer and they wanted almost $7 a piece for flywheel bolts and $5 for the cover bolts. If i knew the pitch and length im sure i could find them cheaper around town.
