Hi, ho folks,

If you have a leak'n transmission then here is some help to keeping that driveway free of hypoid gear oil. Attached are two 1:1 scale gasket copies of the front and side covers for the transmission.

   Yes, you will need to pull the engine/transmission to change out both, but its pretty simple. I've done two transmissions. Just make sure you watch the transmission lever operating forks. Pull a little and look, pull a little and look inside the cover and you will see the reverse and forward gear operating levers. Make sure you know the position of the shaft once you start pulling out the access plate with the attached shafts and forks. If is best to put the transmission into first gear, that way if you move the shaft you only go into second and not 4th gear to out of position (you'll have to pull the plate off and move the lever back into 4th 'c' looking assembly and 4th gear. I've learned my lesson on this one)

Re-install in the same manner as you pulled it out the plate and assembly. Do not force the side access cover back into position.

You will also see a copy of the box for the rear transmission seal. This one is real easy. All need are 2 x 1/2 inch open end wrenches to drop the driveshaft and your choice of implements to pull your leaking seal. I got this seal and three other ones just like it at the Kansas City IBT outlet. Total time for my son to drop the drive shaft and replace seal and re-install drive shaft was ~30 minutes. So you can do it.

Or if you are a little nervous just take it to a reputable transmission shop that can work on old Ford's and Chevy's and they can fix you up. I was out the door at the one shop in Wichita in less than 20 minutes. It was like, zip, zip, zip, with the bolts, pulled in out easy like, saw the fork out of place, continue to totally remove plate and shafts, stuck in new gasket (homemade of course)reassembled, zip, zip, zip with the bolts and out the door. I could not believe it as, I thought I had messed up an irreplaceable transmission.

Any questions drop me a line. Will post blow up transmission assembly from a Datsun Parts Manual tomorrow in pdf format.

Added bonus are the primary gasket for the Nikki carburetor.
