  I found a set of Tarozzi rear sets reasonable, the shifter side rear set controls are on, the brake side is for a disc brake Super Sport so I'm using parts from this kit and a set of universal rear controls to make it work with a drum brake, the spline adapter has a shorter lever than the Tarozzi lever, it should increase pedal effort a bit. If it doesn't work well, I'll have to ruin the chrome and weld to it.
  The seller didn't send the brake lever spline adapter for the disc master cyl. set. Neither of us knew it was special for the Tarozzi levers. It's on the way now.

Will you install a disc rear at some point Don ?

 I'd do it now, but I'm too attached to my drum brake 18x3" Lester mag. I have a drag bike frame that will likely go with a disc rear, it has a disc Henry Abe wheel. For now, I wanted to see if my old legs like the rear sets.
 The tote junkyard contains both 76f and 78F rear swingarms with the brake and frame parts.

 The levers need to go down more but seem to work, with the short brake arm it takes a lot of pedal force. It shifts a little odd but it might take adjustment and me getting used to it.
 I'll work on the adapter plate more and paint it, this was just to see if I like it at all. The brake side was made for a 750 F1.

Don, I usually clock the levers and linkage above the peg on the brake side.  Also for more leverage, get the lever 90 degrees to the pedal (or as close as you can) and make sure the actuator shaft lever is parallel to the pedal lever.  You can change the angle of the pedals by changing which hole the lock pin is in.  It's kinda tricky to get your head wrapped around how it works without playing around a bit.  Also, if I was setting those up for drag racing, might be time to make the switch to gp shift pattern 1 up 4 down...can easily be done with that shift linkage.

In general, old guys look at my bikes with rearsets and say "Isn't that uncomfortable?"  To me, it's more comfortable to be in good control.  Remember don't rest on the bars with your arms locked.  Keep elbows relaxed, support your weight with balls of feet on the pegs right under butt, squeeze the bike with your knees, and support your upper body with your abdomen muscles.  Up above 50mph the wind kinda takes over.
If it works good, it looks good...

 Since the brake linkage is 1/4" threaded rod right now I thought it should be pull rather than push. It still needs to be shortened, the correct Tarozzi lever is on the way but it is for a disc m/c. not sure if that will fit at all. I'm in test mode until it arrives.
 Thanks for your insight, I'm still learning. 
 Edit:
 The brand X frame side splined brake lever replacement is too short, I really need to stand on the pedal to get much rear braking. It's like my first drag car, the PO used the parachute every time even on a long track, it only had a 2-1 pedal ratio. I got a nice clutch pedal from a rambler and made a 6-1 brake pedal ratio it stopped really good after that.
