518 Swap Issues at the crossmember

Ok.. So the 518 goes in pretty easy in place of the 727 However...The speedometer cable is not in an ideal location. Attached are photos of what I came up with to solve that issue. Move the bolt and grind the brace.

Omg, you overcame quite an issue, any chance you can find an angle drive? ( kinda too late I know) lol
Yep...there is always something that needs to be done to make non stock things work. Thanks.

The Angle drives are huge and would not work.

Moving the bolt down was was the best solution...ultimately I think the Engine Tranny needs to move back about an inch to be perfect. However that I am sure will create a whole new set of issues. The O.D. is really nice and worth all the hassles though.
Have you put the tans. in yet. How did it all fit. Had to change my cross member from auto matic to manual. Was not that big of a job. Good luck and keep rolling. :thumbsup:
I’m preparing to install 46RH in a 1968 Charger. I’ve purchased a upper loop from Hooker for this specific transmission. I think I have the exact lower cross member that you have. What was your final drive line pinion angles?
