Also has anyone factored the cost of modifying the trans tunnel or the loss of perceived value with a hacked up cross member?




Well if you can't manage the tunnel/crossmember mods yourself, then chances are you can't fab your own trans mount for the 518, and chances are you can't build your own 518 either. So if you have to farm all that out, you are probably at the same $ level as a gear vendors.

FWIW, the OP asked about a 72 charger. A 72 charger will not need the tunnel or crossmember modded. A 70 or earlier b-body would need those mods. If you have a car that would need the crossmember modded, and you're not comfortable with that, then yes chances are you would be happier with a gear vendors or a chevy 700r4 based auto like the keisler 4-sp auto. Also, from what I've gear, the gear vendors units still do require you to your tunnel for clearance. You don't have to and but it's not a straight bolt in either from what I've read.
