Default 351e/TH400 Connector

I just purchased my first old vehicle and it had a rather sizeable leak in the transmission oil pan. It has 2 rods connecting the engine and transmission together that also tied the bell housing tight. When I dropped the pan I realized these connecting rods had rubbed a hole in the side of the pan so I ordered a new pan...no big deal. Well the new pan doesn't allow enough space for the connecting rods due to encroaching on the bolt hole (obviously an aftermarket design to fit a TH400 and not accounting for this vehicle)

My question is how necessary are these brackets. They appear to tie the whole system together and I assume due to the amount of torque this truck has, but I am not planning on doing any hauling.

I went ahead and put the new pan in and buttoned it all up and drove it around a little and all seem fine. But do I need to just order another stock pan and get the brackets put back on before my transmission falls out the back?

Bend them and modify to fit or leave one or both off. If they are what I think they are, they are for 4x4 application to a NP205. The motor and tranny should have no real relative motion, they are bolted together, so I don't see how it rubbed except for vibration or they were loose?

Those sound like the automatic tranny adapter support rods. I'd put them back on.
