sorry if any of you guys were offended ,  i just got my jeep back today ,i took it  to a local garage   2-days and   $250.00  bucks  later it is  done .first time driveing it since december,   with the  4:10  gears  and 4.0 h.o  is a great  combo,  this weekend  i will be in the woods  trying  it out.  if i have time i will let  every won khow how it was.    seeeeee-ya  

Where did you get the dooner ,I mean i have been looking at other models cherokee grand cherokees for engine dooners for my 89 yj because there are a whole lot more in the bone yards to choose from.Any recommendatios I,d like to know seems down here in florida they throw them away with no remorse

So the 410's are good? I'm thinking about changeing up mine as well  

I GOT LUCKY A FRIEND OF MINE BOUGHT THE JEEP   A  1992  WRANGLER  THE JEEP WAS ROLLED  ,HE BOUGHT IT  TO FIX BUT CHANGED HIS MIND WHEN HE REALLY LOOKED AT IT  .   SOO I BOUGHT IT FOR WHAT HE PAID  FOR IT.  BUT LOOKING  BACK  I WOULD NOT DO THIS AGAIN ,WE HAD TOO  MOVE MOTOR MOUNTS , AND SINCE  I CAN;T WELD SOO GOOD I HADE TO PAY SOME WON TO DO THAT.   ALL SAID  I SPENT   $1.200.00  BUCKS   AND  DID ALOT OF  WORK  MY SELF  AND   SOME  FRIENDS.  

4:10 'S  WITH A SIX  IS A GOOD  COMBO ,  ONLY HAVE 31'S  [FOR KNOW[ ,BUT SOO FAR ON THE STREET IT'S GOOD ,ON TUESDAY WE ARE GOING WHEELING FOR THE FIRST TIME WITH  THE NEW MOTOR  .  IF  I KEPT THE 4- BANGER   4:88'S ARE  A GOOD CHOICE.
