85 720 motor mounts.

[Smoking Joe]

I need help in locating new motor mounts for my 85 720.  I have ordered two different sets that were supposed to be for my truck. The first set was not even close.  The second set is close

 But are not the same.  
 

the stud that Mounts to the engine bracket is higher than the centerline of the original.  They also stand approximately .160 thousands higher/taller than the originals. 
 

further the locator pin on the engine side is slightly off and will not fit into the original engine bracket. 
 

also the locator pin on the frame side

is larger diameter and will not fit into the frame in the passenger side.  
 

again these are very close but just enough difference that if I were to make them fit I’m afraid the engine would sit to high in the truck. 
 

hopefully some ones can provide a place to order the correct ones I need.

I've never heard of after market MMs fitting correctly, hell the original ones are often a bitch to get right when installing the engine after having it out.

I’m sure you are correct.  I would use the original except for one of them is broken and I’m sure the other one Likly sagged from the years of weight and heat that they are subjected to.    I will ask you opinion on installation of the engine. Would you recommend installing the engine and then the transmission or installing them as a unit

Six of one half dozen of the other.

 

If you have lots of overhead room and a chain hoist and use an adjustable level to get the transmission steeply tilted down enough, you can put back in together.  If doing separately, put the transmission in first without the engine in the way and support it in place then mate the engine to it.

Did you take both of them out as one unit? It’s a lot easier to mate the engine to the transmission while they’re both on the floor.

Both Photos are of a new and old mount for comparison.

OK, I understand, they appear to be close, old MM may settle and be shorter than new MM, just do what you have to do to install them, I have forced 620 MMs to work on a 521, and it was not easy, if a hole is not quite big enough I would make the hole slightly bigger, but I would not change the frame, only mod the motor mounts.

 

You started another thread also, I do not fix what is not broke, there is a point when if you have enough vehicles of the same type, you may have an extra for parts.
