Cam, I'll send you the right drum either tomorrow or Monday. Use the new band from the kit. The brake Alex linked too won't work because the through hole I'd needs to be bigger to clear the tube. If not, the wheel will be too far out, and the brake too.
As far as that hole where the pin should be, get the correct size bolt that goes in the brake band. Get a grade 8, or at least 5, and 2 nuts, 2 washers, and 1 nylock nut. O,and a small diameter piece of tube that fits over the bolt, but small enough that the brake will seat good up against it. Put a washer on the bolt. Put it through the hole. Add the other washer and one nut. Snug it up and set the bolt where it needs to be. Now tighten the crap out of it. Add the second nut, and tighten it up against the first one. Add the tube and then the brake. Put on the nylock nut, just enough so there is no excessive slack, laterally.
The tabs in post #34 are the rear body mount tabs.
Of course!
the tube's in the way for the brake plate...
The drum itself will fit though... just as a 4.5" band brake drum..
The hole is in the wrong position for a 4" brake band..
That's what I always forgot to measure and take a pic of...
Know what.. I'll take a pic NOW..
hang on...

[EDIT]
So.. took pic..
crappy.. forgive me..
I'll add older pics ...
now..
My rest-pin for the band brake has a center to center distance of exactly 2.5" from the axle.

the hole (mine) was used to align that shabby plate you see,
to prevent the band from slipping off the drum.
(that's not factory obviously)
as it misses the sapcer (just like you do atm )

That's the kart I sold. Look at how the brake is set up. That kart was all factory, minus the butterfly steering wheel and hand brake/gas levers....
Yes cam, just like in that pic you posted.....except I'd use a piece of metal tube. Well,I guess pvc would work in this case. It's just a spacer, and wouldn't see any real stress/force....
I think one of Cam's problems is mounting the drum to the wheel.....(that's where the "the bolts don't match up and I can only mount 2, and I don't think that's enough".....comes in....right bird?
But....yeah....mounting points are another issue....and this is one of those threads I just wished I had kept my mouth shut....sorry Cam....
Well Cam, that's not rocket science.. it's the wheel, the spacer, sprocket and drum, then either six or three bolts to mount all that together (yes, three bolts are enough )
just make sure that you do not crack the wheel with the bolts, such wheelhalf is not cheap anymore (with the tapped holes)
As soon as you got the drum, it's as easy as counting to ten
But do me a favour and measure the distance of your hole from the center of the axle,
that way we can tell if you need to drill a new one (or weld a pin) or if it's just a bolt you need to fix the brake band.

Have no idea what you just said up there ..... I got lost somewhere.....
Cam ,wait till you get this drum, so you're not racking your brain. It will all make sense, when you got this part in your hands, and can actually see where and how it all fits together. I'm pretty sure that hole is in the correct location , in correlation to this drum and the bands positioning.
