Broken tranny mount after 4406 swap....what can be done?

[Josh C.]

Great idea, looks good.You have a doubled up skid plate because you felt the original single was/is too flimsy?

I know this is 10 years too late but for those that find this looking for solutions and ideas...

I did something similar to what Turdle did. I had maybe 1/2 inch (at most) of space between the Tcase and the skidplate. I had some dense black rubber foam that was used as packing material in a crate that was delivered at work. (kinda like that black pad they sell for kneeling on at Home Depot etc). Anyway, I cut a piece about 4"x5" then raised the Tcase with a jack like Turdle did. I slid the foam between the skidplate and Tcase and lowered the jack. The Tcase "squished" the foam enough to hold it in there and the foam provided some cushion for when the skidplate took a hit.

That’s what I’ve been doing as well

I use a f150 mount either stock or urethane and I mod the factory crossmember to accept it

I also move the t case to the pass side 1/4”

I recall you mentioned this during the 8trac build and probably others. Do you just make the slots 1/4" further to the passenger side when you drill/cut them into in the plate welded onto the reduced-height crossmember?

 

[410Fortune]

Yes

So the
Mustang/f150
Mount uses completely different mounting stud locations of course. So I find center line of the old stock mount and the new mount, move it over 1/4” To pass side and then drill the holes/ slots for the new
Mount.

The f150
Mount is 1.5”
Taller then the factory 5.0 Mount so I cut 1.5” out of the factory crossmember height and make a new plate for the top.

I move the t case over 1/4” because we believe all these 5.0 swapped trucks with the 55-65’mph vibration is due to the rear d shaft angles being too perfect with the 4406 and its slip yoke rear d shaft.
So far so good!
