Hello I picked up a running 01 mojave for $500. It makes clunks in 2nd gear only, so assuming it's the gear missing a tooth. I have the motor pulled and noticed after cleaning it up that the left side case has been jb welded pretty heavily so I plan to replace the case, are their any years that will only work with specific years... I ended up finding a 02 set of cases for 75 so hoping I won't have any issues. My plan was to still use the 01 stock right case and then use the 02 left side case any reason this wouldnt work?
