drag shocks

[69trk]

I have a 69 short bed cst with a 431 big block that dyno 684 to the flywheel. Also has a wilsons turbo 400 with transbrake, aluminum drive shaft, new manual disk brake set up ,mosier 33 spline axels with full spool. My question is that i can't find anybody that carries drag shocks for the trailering arm with coil springs suspension. I have lowered the truck 2 1/2 in front and 4in. in the rear with shock relocaters on the rear from early classic. It ran a best of 11.96 at 110 mph. with a 1.76 60ft. It had 16 in centerlines with worn 10 in. hoosiers that were spinning off the line. I have sinced replaced the tires with a 12 in. qtp hoosier which i had to make wheel tubs wider. Haven't taken truck back since i replaced tires. Should hook better with new tires. Also does anybody know what this truck might weigh? There was a similar truck at the track and he said that his weighed 4800lbs.
