T86 And D18 Extra Mount Plates?

I had this extra plate under the bottom of my T 86 case:

Here’s how it looked when I pulled the transmission off, with sliced bolt heads and all:


and this extra plate on the bottom of my D18 case:


are these things stock? Or were these added by the previous owner for unknown reasons?

There was some funkiness going on around the transmission crossmember area that I am trying to undo.

 

Those are both nicely done. So I guess - stock.

 

There’s a lot of good info in this thread:

Transfer case mount? D18

Seems as if these plates that I cleaned up are stock under the T86 with a 225 V6 & D18. The “z” plate seems a little twisted - wondering if it got torqued badly at some point.

 

I had both on my 68 with the v6/t86/d18 combo

 

Thanks. And no side frame rail mount to D18, correct?

 

nope it was to the cross member My 71 had the frame bracket

 

That "Z" bkt is a torque suppressor with rubber mounts that bolt to the D-18 and then down to the far right side of the cross-member. The bkt is mounted between two rubber bushings.

 

omix-ada part

 

This is what I’ve got in my parts box:


Is it different? Looks the same to me and the PO May have gotten it from Crown instead of Omix.

 

looks the same to me. the cup for the smaller bushing may be attached to your cross-member still.

 

I have that same Z bracket on my '67 V6 w/ T-86 and D-18:



The bolt is in backwards, though, and it doesn't have a castellated nut....looks like I need to replace it with a new bushing and bolt:
