    '79-later are all the same...and have the same mount spacing.

    Yes, sorry forgot to put the details but the original owner of my bike managed to get a k0 bridge on it

    Certainly not the worst conversion job I've seen. A K1-1978 top tree + bar clamp would have been better but this looks workmanlike at least. For your purposes, you really want a `79-`94 top tree; unfortunately, they're not super-common. Alternatively, you could use a K1 type, have the bar clamp holes welded, then milled flat. After which you'd redrill the bar clamp/riser holes in the proper locations for fixed bars. FYI, you'll need to source new cap bolts for the fork legs. Dratv has them, new.

    Thanks for the info, I'm currently sourcing one from a local guy out here named ctskipper, he said he might have one, if he doesn't have one I'll go the other route you mentioned

    If he doesn't come thru, let me know. If he does come thru, please post up a few pics of it so I can identify mine. I think I have the plate, but with some ATC clamps.

    Kirby the guy didn't have the plate, but this is the plate I got off eBay and it was wrong to, so my local guy traded a top plate for mine and welded up the holes so all I have to do is drill the plate for my risers.

    This plate is off a atc70

    Mine looks pretty similar to your pic.
    So the one in your pic is from a ATC70, and it is NOT right for your CT70??

    Here's the parts I have. I think the plate is from a 79. The risers I took off or a K1 CT70 front end.

    Yes it's from a atc70, its not right for mine as mine measure 6 7/8. I took measurements from center bolt to center bolt on this one and it comes out to 6.5in. I believe the k0 top plates measure 6 1/2 and the 72 and up measure 6 7/8, so the atc70 top plates will fit on the k0 if you want to put mx bars on it

    I got some measurements on mine. I got 6-13/16 on the legs centers. I'm gonna label this on as a 79-94 part.
    Those holes are 17mm...about 9/16"
    The total length is about 8-9/16.
