I'm running a 5.0 with the M5ODR2 and no modifications were needed. It bolts right up--mine is a 4x4 but that shouldn't make a difference.
Tedybear--you have a different problem. The R2 used with the F150 will not bolt up to the 4.0 I assume you have in your Explorer. The 5.0 bell housing has a different bolt pattern.
True, only a 4.0 or 2.9/2.8? would bolt up for the bell housing.
We spent about an hour at the picky pull looking for another one. I did find 1 several months ago, but it had a blown input shaft bearing set. Yeah a little play up and down/side side is acceptable at the front shaft. The one we pulled? Had a wholeeeeeeeeeeeeeeeeeeeeee lotta boinking around with that shaft.
When the OP mentioned the input shaft being a different size, that struck a cord with ours. Sorry for the mis-communcation.
(and me poor spellin')
I'll try the other yard on Wednesday and next Sunday. I wish these guys would inventory product better. (such as, engine size and drivetrain type.)
