Lots of ideas and info even if you don't buy their kits.

Way too complex than it needs to be...I'll use the existing trans so I don't have to change anything there.

I have a set of LS engine mounts that I can use with early Ford biscuit cushions. Same bolt pattern on the Hemi and LS.

I can fab my own mounts on the xmember.

I'm just spitballin here...if it's more than a G-note to do it I'll just rebuild my current 5.2.
