Yester day me and my buddy rebuilt a pump head that hes got on a old school roadster pump with a street rockford pump head. It is an #8. But anywayz we was running transmission fluid in it and it worked fine . ( oh and hes got 10s on the back) . But anyways, experimenting like i always do i put some thicker fluid in the pump. and when i raised it up both of the leaf springs popped right in front of the lowering blocks at the same time in the same place. So i guess now i am gonna have to 4 link it and i have been dreading that for a while. Any suggestions? or tips.
