    t86 is out finally, I had to wait for the snow for some reason, will a t90 repair kit work?
    What throw out bearing part number please. Help?

    There is more to learn here than the title shows.
    Since before Fall of 2015, I have been looking for a T86 that came with my 225 V-6. The front shaft has to be a 1 1/8 inch 10 spline shaft. (No 4 Cylinder front shaft will work here, It measures .94 and is not 10 spline.) I found three this year and all the deals failed. A long time ago a guy sent me a crate that I forgot about, it is a T90A for a 4WD 1960's truck, there is no drum brake behind the BIG HOLE Dana transfer case. I tore the T90A apart and ordered an overhaul kit for a T 90 to put into the T 86 case. Keep everything from each case in a 5 gallon Tupperware type plastic storage bin, If you get interrupted as often as I do you already see the reasoning. Every part, gear, pin, bearing gets a manila tag connected, all parts get written on them with a paint stick for orientation. I am using the 1966 version of the Motors Manual for identifying parts for organization purposes.

    there is an awesome link http://thecj2apage.com/forums/t86-t90-gearswap_topic33377.html

    Are talking about a small parts kit or an overhaul kit?

    Small parts kit includes snap rings, thrust washers, bearing spacers, and needle/pocket bearings but no gaskets, seals, blocking rings, input or output bearings, shafts, etc.

    No. Input and output bearing(s) iirc at least one is different. I cannot remember for sure on the small parts kit but looking on some supplier web sites like Walck's or Novak should turn that info up. The cluster/counter gear shaft is the same iirc. I would suggest just ordering the parts by application so you get the right ones if that's what you are planning on doing. If ordering from someone who knows these transmissions they should be able to get you the right stuff.
    I'm going to move this to Tech also as it's really more appropriate there and may help others as well.
