    Thanks for the replies,

    The rear axle in the Roadster is a open diff and the the stock engine at 93 hp it is a one wheel wonder . The LSD is very expensive and really hard to find much less keep clutch packs in it. Other owners use RX7 rear ends, but just about anything will work having it cut down. Talked to a friend who builds Toyota trucks and he thinks the light weight truck axle that is undesirable for large tires would work good. Unlimited supply of OEM LSD and large selection of gear ratios. I'm leaning this way but thought it would be more efficient with a quaife Fnr.
    Thanks Jeep401 for real world experience- I'll put that option to rest, and go with the seemingly unanimous opinions of the rear axle with the inline reverser.
    Been a while since I posted pictures on this site, I now use a iPhone and the pics are too large. Got a photo bucket account and will work on getting some pics of the car and build.

    Sometimes if pics are to large you can email them to yourself and it automatically cuts them down to less bytes. Then they post. It has worked for me.
    Now that NOBAMA has PROVEN he is the absolute WORST president in the history of history Jimmy Carter can thank him for stealing the dunce crown.

    Lets hope the next guy repeals NObama care along with the rest of the stupid crap this blight on our windshield has done.

    Alright Nuts, lets try this.

    Looks like they are click-on pictures.

    I just weighed the car, came in at 2,065 lbs. With taking out the cast iron engine and trans, hopefully I can keep this thing at around 1700 to 1800 lbs. Should make the car scoot.

    Ditch the rear axle for something stronger with more parts availability.

    If you go the Toyota light truck route (which I would suggest), I have a limited slip diff for a Tacoma that I will make you a deal on...........

    Lug pattern is easy to change. finding gear sets and posi's for obsolete rear ends is not.

    I was going to suggest a Miata rear end as well. I would graft the whole rear clip in. Performance parts are readily available too. Grafting the front suspension in might not be a bad idea either. Better brakes all around on top of the "modern" suspension would certainly be a good idea with the busa powerplant. There are some FAST Miatas! I drove one once and was very impressed.

    [/IMG]Well after the Holidays - daughters wedding ect., I'm finally starting to tear down the Datsun for the swap.

    Busa Datsun-077-1-.jpg

    Pulled the motor and started to pull body panels off, oh the rust What else would I expect from a almost 50 year old car. I'm going to replace the floor boards but leave all the body work until after I get her on the road - maybe next winter do the body and paint.

    Pulled the engine.

    Busa Datsun-a021-1-.jpg

    Engine mounted transverse and will have a drive shaft going back to the X bracing to a Yoshi supplied Reverser and then to the stock rear axle for now.
