I just got my motor together after putting in the new rod. And this was the first time I've gotten to play with it since the new rings, heads, carb....etc. The drag radials don't hold at all anymore. I give it some gas at 25 mph and the tires don't want to hold. I'm going to get rid of my SSM's, but I'm too cheap to pay for Caltracs. Slicks would work, but that would mask to problem. I want to make it difficult on myself. I want to run fast on drag radials, too!! Here's what I got. I got the directions on the internet on how to build the caltracs and I've got the rod ends already(my local speed shop had them in stock!!!!). But I need to know from someone who has them, what are the measurements. I need the center to center on....... The eyebolt to where the rod end connects and.... from aprox. the center of the axle to where to the rod connects at the lowest part in the back. I would gladly be you best friend forever. Thanx in advance. 

....but i would glad to take your SSM's off your hands 
, so I say get out there and do the measuring yourself. Its a good chance to do some math and have fun with a tape measure, plus it makes the whole project more "yours" as opposed to a buy-it-on-credit, bolt-it-on-car paradigm.
