attatch it on the pinion even with the pinion gear....
then to put it on the frame set the rearend on jackstands so that the weight is on the rearend like its on the ground and keep the j bar level with the rearend

hi guys. scott, alex opens on the 24th, but starting time for the first couple weeks is 5:30 not 6. we did switch from nascar to wissota ('bout time!!!) let me know how the testing goes as we have our car set up to go j-bar or shorty bar. i think if the track dries out as bad as it usually does and is smooth the short bar will be the way to go. our j-bar is 21" and we designed the frame mount so our shorty is still 18" so it might not be as erratic as some are.
lil' blue, last year we started out with 24 to 28 mods each night but towards the end we were down to around 18 (our problem was non of the fast guys left, LOL) hope to see ya both there, john
