This topic is going OUT THERE ...and there is no-need for that.

As long as the pan-rail is straight ....and you do not OVERtorque the bolts ... you should not have a prob.

GRINDING the chrome off ... .... uNless the chrome is peeling ...it should not be an issue. And even then .... just use some Hi-Tac gasket spray and some RTV ...and all should be well.....

And lastly ... running the bolts down on the pan ....is done in INCH pounds ...NOT foot-pounds.
