Installed my 390s!!
 

Finally installed them a half an hour ago. No whining or any noise for that matter. Still need to fix my speedo gear though. Looks like another job for another day. Back lash is at .009 which is decent. I haven't got on it yet cause i"m in break in period for my first 30 min wait. So I'd figured I'd waste a little time to let you guys know there in now.

I'll keep ya updated in how they are. If weather is good I'll have to go down to the track Wed night to try everything I've put in!

Thanks! We found out that I had 327s in her before swap. I guess someone put an automatic rear end in her or something cause it was factory logos. Just finished my break in and def. feels lighter at the wheel. At 55 my speedo shows 70 which kinda sucks. I have all the speedo correction equipment but looks like another long process to put in.

if you have to swap the gear in the tailshaft then it may add some time but I'd start with drive gear on cable and see how close/accurate you can get it with just a change there;)
