    The reality is that unless your sourcing NOS bearings from somewhere stateside just about all the bearings being made now are coming from India , China , Vietnam & beyond...............QC is an issue on some brands.

    We have had a look at the gearbox again and have found a way to get the 23mm bearing to fit in place of the 20mm. It will require a little (minor) machine work but nothing major and from what we can see by the existing shadow marks on the gears will actually make the contact pattern more effective.

    This will allow us to use the better Jap bearing at both ends. I talked with Novak about the idea and according to Novak it hasn't been done before but they liked the idea and thought it was a sensible option as they too dont like the cheap Chinese bearings which out of interest are the same in their kit. Watch this space.

    On another note, what is the consensus on the U style shift pattern Dana20. This is what I have in the box/transfer setup. Any pros/cons.

    I did a search for the clutch kit, picked a 75 J20 5.9l with manual. But it's given 3 different makes and they seem to differ if you go up/down a couple of years. How do I know which one will suit the T18 with 19mm pilot bearing? Below is the list of what available on Rockauto

    I would go with Luk or Sachs.

    In a previous post I looked up the tag number 5358285 and it's for a 1979 258 J-truck T-18. The bell housing is the same for a 258 or a 360; the only difference between the 258 and 360 bell and adapter should be the length of the input shaft and the use of a thicker adapter. The thick adapter moves the shifter to the rear in the V8 application, making up for the longer overall length of the inline 6 compared to the V8. I would pick parts for a '79 with a T-18 and 360.

    The pilot bushing is a 3213751 for all '74-79 10-20-40 (wagons and trucks) with manual transmission. Apparently there is no diff between 258 and V8. You need to match the pocket in the crankshaft (V8) and the pilot tip. This app should do it.

    The cover for the '74-79 10-20-40 is a 3184955. This is an 11" cover. I recall the 11" clutch will fit in the 258 or 304 applications which originally got the 10.5" clutch, but I can't tell you what the differences are in the aftermarket applications. The 258 used a 10.5" clutch in most applications, but it could have used an 11" clutch in the J20 - that application never was offered in the USA. The '74-79 360-401 plate was a 3184867. The release bearing is a 3190517.

    When I was rebuilding my T-18, I bought most of the parts from Parts Mike in California. Great place to deal with.

    Before going too far see if you can get your hands on a Tremec book;
    Bulletin No. LD18-0410-0199

    This is a very comprehensive reference with diagrams, exploded views, OE part nos. and covers more than a couple of the venerable as Väinämöinen T18
