yes I removed the egr pipe off of the downpipe using a pipe wrench and a long breaker bar. NIssan makes a special plug to go in the hole its about 12$ part #14052-21R00 available at any nissan dealer.    I also removed the studs from the downpipe and used short bolts to bolt my exhaust up to it instead of the  studs. I will get a picture when I get my truck out of the snowSmile

yes I used the stock sr20 transmission.  You will need to carefully measure your driveshaft. You will need to put the truck up on jacks with jackstands under the rear axle.  you will need to cut the dust shield of you factory driveshaft. slide the yoke in but not all the way. There is usually a dark spot on the yoke where the seal normally sits and that will give you a reference point.  The yoke needs a little room to slip in out out of the back of the tranny.  Too little and the shaft will fall out or wont engage on the splines and too much and you hit a bump the driveshaft will dig into the back of the tranny.  Take careful measurements and use your head.  remeber measure thrice, cut once!

yes I used the carrier bearing because I couldnt afford to have a custom shaft made.  You NEED to measure yours properly because of minor variations, there is no possible way yours is exactly like mine.  Jack the truck up with stands under the axles.  leave the rear shaft (carrier bearing to diff) in place.   Hold your driveshaft up and see how much you will need to cut off.  Remember you need atleast .75 in of the yoke slipped out to allow for forward movement when you hit bumps.

yes you only need to measure and shorten the front shaft (the shaft that slides into the transmission)   you have to take the carrier bearing out to get the front shaft out, then you replace the carrier bearing and rear shaft.  Then you can slide the yoke into the transmission and hold the shaft up to get an idea of how much you need to cut off.     You will want to shorten the driveshaft ON THE END, DO NOT CUT IT IN THE MIDDLE!  

you will need to carefully cut around the weld bead to remove the yoke fromt he tube.  cut about 1/16" downinto the weld.  Thsi will allow you to slide the yoke out of the tube. You can then begin to measure properly.   slide the yoke into the transmission but not all the way in you need the yoke to be able to slide into the transmission when you hit a bump.  You can use the marks on the yoke where the seal has polished the metal to get an idea of how much you want sticking out fromt he transmission,   normally about .75 inches.    I want to make sure that you are understanding all of this so you dont mess your shaft up.  If you have any questions what so ever please ask them.  You will want to cut the weld that is on the  slip yoke end    (the top of the picture)
