the 74 z1 turbo project again

Exactly what dimensions are you looking for? I have a double clubfoot with the lower wheelie bar mounts.

theres going to be tubing braces running from bottem of steering head following the origional stamped gusset under steering head to the downtubes to about 3" below where current gusset is cut off

You are doing a bang up job there Plum.
That bracing should make a big dif. My 1327cc bike felt like a slinky when i put it through the gears hard (even with bracing). I cant imagine what your turbo must have felt like? :woohoo:
Just a thought. I had trouble with the tank fitment, interfering with the braces. if u haven’t checked already, u may want to test fit the tank.
What do u think about some more bracing under the top rail in front of the seat? I saw it on a Sanctuary bike , and thought it was a good idea? You have every brace i have ever seen except that 1. Have u seen that Sanctuary add?

I had problems with the tank fitting on the frame after I put bracing in that area too. I had to "persuade" the brace to allow the tank to fit better! Good idea to check that before you paint. As far as the c-c measurements, usually wheelie bars are built to fit each set-up. I measured three arms I have and they had 4",6 1/2" and 7" c-c measurements. I know the dragbike has the 6 1/2" c-c and the bars for that bike will only work for that bike. Pingel bars are adjustable, to a point, to fit different set-ups though. You can either build your bars to fit your set-up or buy some bars and weld the mounts so they fit those bars. Every bike is different. My dragbike mounts are under the rear axle and one arm has the mounts about 6" in front of the axle. Why do you need wheelie bars? You're not going to run sissy bars are ya? Training wheels on that turbo? LOL

I bought precut brackets from Pingel and had them welded onto the bottom of my swingarm. I also had struts made with a small bracket only at the bottom of the strut. I really worked out well. Most bars are adjustable so you should have some wiggle room.

I'll add some pictures of my old set up if I can find them.

OK, here's a shot of the swingarm bracket, but not the struts. The arm is gone so I can't offer a measurement, sorry!

Here are a couple pictures of mounts on the arms I have. D&G Chassis also sells mounts but I don't know what they look like. I know all their work is top quality though.

Another...
