Kinda after the fact here, but I'll shoot pics later this afternoon and post 'em. They work pretty good on the stock multileafs!

you can have very good luck clamping the front leaves tight, if you need more i ran a set of the j bolt comp engr traction bars for years and they hook hard, the newer slide a link style bars look even nicer.
check you pinion angle you can get a lot of traction by angling the pinion down a few degrees, i wouldnt drive it like this all the time but for a track only day its worth swapping in some angle shims for a good launch.

Tony..If it isn't too much trouble, I would like to see the pics.

Thanks for the info Indy.

I've never noticed a traction difference with pinion angle...I've played with it on our Camaro, and had custom sets of billet wedges made, and the only thing I can see it effected is u-joint life and MPH...you just want it to end up close to 0 as you add power...

found some traction while setting up a 9 sec 68 camaro, running leafs and south side machine bars on a 10 inch slick, ran 2 degrees down when the track got loose, used it more as a tuning aid than anything else. i always ran mine @ 0, 12 sec 69 small block car

Sorry for the delay in pics...busy week. These clamps work great. If anyone wants, I can pull them off and get actual dimensions. They're sized so there's about 1/2" clearance to each framerail.

During the SS&DI magazine test back in 1969, Ed Hedrick used 3 clamps per side on the Yenko Camaro demo car. Car got into the 11's.

BTW, Ed is an engineer, who helped Grumpy with much of his chassis/driveline problems. At the SCR Ed spoke about the time Grump watched as Ed launched Grump's car several times "inside" the shop.

A little off the main topic, but I also found it interesting when Ed was talking about the natural frequency (vibration) of the driveshaft and what engine rpm it happens at...

Thanks Tony. Yours look almost identical to what I made. You have a PM...Tony
