Notching K-frame for Milodon Pan

I have the same pan except mine is a 30935 in my 68 416 Barracuda. Are you using the stock K-member or a RMS type? I had to notch my pan to clear the rack and pinion on my RMS front end.

Sorry, this is a stock early frame. Just wondering if you chop it if you need to reinforce other areas?

Thanks
