Conflicting front lower control arm bushing part #s

[Fox W.]

Ran in to part confusion.  GM Parts direct shows three different bushings fitting the 89 for the same diagram position:

 

It is for part #5 on the below diagram.  Part in person shown in red.    

 

The numbers are:

22528801

22528799

22528668

 

And their page shows all of this for #5:

 

#5	22528799	Insulator Lower Control Arm Front Bushing 1ST	$20.35	$12.99
#5	22528801	Insulator Lower Control Arm Front Bushing 2ND	$9.92	$6.33
#5	22528799	Insulator Bushings INSULATOR; FRONT; BUICK; REATTA	$20.35	$12.99
#5	22528801	Insulator Bushings INSULATOR; REAR	$9.92	$6.33
#5	22528668	Bushings BUSHING

The confusion for me is that in person there seems to be only a single bushing there.  It seems to be part 22528668,  which is the same as Moog K5298.

I'm not sure where they are getting these other parts from, I don't see them.   Does anyone know if that bushing on the 89 is a single-piece, or if it is two pieces?

They list all of the above despite me specifying my specific year and model.

 

22528801 doesn't seem to match anything I see on the car.

Thanks.

 Yeah that is what I thought, I remember buying these in the past.. I am going to say 88912731 and 22528668 are the same, and after market is *5298, since that has the greatest consensus and because the part seems like a single-piece from what I can see without taking it apart.   

 

It is then a bit of a mystery why GM is listing these two as fitting, I don't see where they would go:

22528801

22528799

 

Thanks!

Welp,  22528668 does not appear to be quite right..  maybe it can work, but it is not the same as what is in there now.. it is shorter, without he big flared ends.  It does look like the original is a two-piece system.   

 

Anyone changed these before and have pictures of what they look like out?

[Fox W.]

Thanks, we'll get to the bottom of this I'm sure.

The bushing is one piece as shown below

 

 

 

If has to be pressed in with a special fixture that forces the large rubber end of the bushing through the control arm where it pops out again.
