<< < (3/3)

HodaddyB:
Material thickness: .120" / 3mm
Bracket width: .955" / 24.3mm
Overall height @ forward edge*:1.637" / 41.6mm
Overall height @ aft edge*: 1.44" / 36.6mm
Tab width (side to side): 1.15" / 29.2mm
Tab aft protrusion (from aft edge of bracket): .855" / 22.5mm
Distance between legs: 5.1" / 129.55mm
Distance between tab and bracket**: .090" / 2.3mm

*The bracket "leans back" relative to the upper rails. I apologize for not measuring the angle, but the height measurements will get you there just as well.

**The bracket is fabbed w/ the tab as an integral part. The "tab" is placed in the center of the span, and is raised from the top plane of the bracket by two joggles (one on each side of the tab, of course). Not to be didactic, but if you choose to weld a tab to the top of the bracket, you can simply add a .090" piece of material in between.

Let me know if I missed anything.

Didactic?  No I'm an anorak.  John

I made a new seat bracket but ended up not getting it welded on. Turns out that I have 3 broken mounts and when we tried rewelding them, the aluminum under the surface puddled before the surface would. No matter how much we cleaned the surface, there was too much contamination to get a puddle going. So now I am back to looking for a complete replacement. Or I'll fab a new one up out of steel :|  I did find one on ebay, but it has a couple mounts missing and I don't want to mess with trying to fix another one. 

HodaddyB, thanks for taking those measurements for me.

RoostDaddy:
I have a buddy that just called the other day. He bought a parts bike for the motor and I think he's willing to sell the bare frame and sub-frame.  I believe its somewhere around '86-'88.  I'll check and post back.

Scargoes:
That would be great, thanks.
