Hey i have a 91 rx7 na with a welded diff, i recently bought a s5 turbo diff and i pulled the pinion flange off and redrilled the bolt pattern to use the na driveshaft... problem is i may have over crushed the crush tube when putting the flange back on, not sure yet. If i did, can i fish the crush tube out and replace it while its still in the car? Thanks for the help
