AOD Trans crossmember
I was planning on a Ron Morris crossmember for the AODE I intend to install. In my build post, Eric mentioned that the one he bought didn't fit. Is there a different one out there that others have had good luck with?

Eric, how much modification did you have to do to your original?
I would do some checking. It was my understanding that the stock FMX crossmember fits the AOD. I had read this in a couple of places.

73 Grandé H Code. Headman long tube headers, T-5 Transmission, 3.70 Traclok, Lowered 1" all around, Aussie 2v heads w/ 2.19 intake, 1.71 exhaust, screw in studs, full roller cam 608/612 lift 280/281 duration LSA 112, Quick Fuel 750 CFM double pumper, AirGap intake.

Not horribly so.  Just had to notch it a bit to clear the AOD's pan.

Here's how poorly the Ron Morris bracket fit:

Here's the notch I made in the FMX cross member:

And it fits just like it's supposed to:

Since the cross member is 'U' shaped, there's plenty of meat left for the bracket to maintain its integrity.

Hope that helps!

Nope, the one from the FMX does not fit!
Here's what I used and it was a perfect fit and very sturdy at that!

Do you not see my pictures with my original FMX cross member installed (after I notched it)?  whistling  Cool

I actually picked up that Ron Morris cross member (first pic) from PATC when I ordered my stuff.  If they would've had the bracket you have available, I would've gotten one of those instead.

Thanks guys. I have updated my material list to the one Mike used.
Thx Eric for posting that info/picts.
From what I see on the link, for the +-€250 it would cost once at my door, when I'l install mine, I'll either make one or do the cut it as you did.
It's strange tho, just like @73pony, when I did some research on the subject, I've red many times that the original FMX fits with no mod.
Are there diffs in AOD shapes/bodies?

73 modified Grandé 351C. Almost done. 
71 429CJ. In progress
My pleasure!

I agree - for that kind of money, I would just modify the FMX cross member and go from there.  You might improve on this by welding another layer of metal to the flat part of the bracket, as well as trim the edge on the right side of the notch (in the picture... it would actually be the driver side), since it rides a little close to the side of the transmission pan.

It doesn't actually touch, but it's really close.  I haven't seen any evidence of touching, but when I get a chance, I'll be trimming off the edge a bit.

Plus, I think it might be almost impossible to pull the pan without supporting the transmission and removing the cross member... let alone getting to that last bolt. rofl
