dropped floor pans

Rails and members remain.

The idea is to drop the mounting plane for the seats. Not necessary, or at all advised, to alter chassis reinforcement structure.

Prior to undertaking this modification, you can lower seats some by removing some spacers that were OEM, and some owners pick one seat position, and then remove seat slider rails and anchor seat in desired spot.

Most of these cars are one driver cars so seat adjustment fore and aft is not a needed option.

My car when it arrived from Florida, had the frame of the seat removed, and the bottom cushion velcroed onto the floor and the back velcroed to the rear firewall !!
I am not saying it was good, as it would move around when you got out.
I screwed the base and rear to the floor and rear.
Means once done you can't adjust it, bt as Larry said Panteras are not really multi driver cars !!
One thing i did notice i had to space the back of the seat a bit so the seatbelt did not catch on it.
much easier than cutting the floor in my opinion.

The drop pans usually do cut out the minor chassis member that runs front to aft near the tunnel. Just the section from the rear bulkhead to the center cross member, otherwise you are extremely limited to fitting a very narrow seat in the dropped area.

I just made my own drop floor pans and installed. It really isn't that difficult and beats $300 each from the vendors. Cost $79 for a 4' x 10' sheet of 18Ga cold rolled steel.

I did the same ... completely removed the supports between the bulkhead, fire wall and the 2 rockers .. I used 18 ga sheetmetal ... and with the roll cage and reinforcing the rockers with plate steel .. which I have yet to start ... and added 2 box frames under the fire wall and bulkhead ... basically I duplicated the same set up on my later 9138. This is not complete ..but its 1/2 way there.

and the top view

Tanks for all the responses. ive decided to remove my floor pans and the frame rails from the firewall forward to include the cross brace but leave the rails from there forward, install complete new frame system at the center tunnel with 2 rails and at the rocker panels and tie them together with new cross brace and also tie into the original frame at each end. seems easiest because the rust issue will be completely eliminated. larry
