1969 911e floor pan questions?

Hey folks, I am doing front floor pan and fuel tank support on my 69e. I have removed all of the old pan with the exception of a double thickness flange at bottom. I was wondering if I could leave flange remaining on bottom? To provide extra thickness to weld on bottom. Also bigger issue, if you notice in picture my laterals are still in place. So the new pan will have to be installed from front and underneath. This becomes a problem with front a-arm support which I would like to leave in for final pan alignment. The supports have about an inch and a half of up and down play, but I need a little more to slide the pan in (clearing the front wall at the bottom). Can these be loosened or removed one at a time? If so, I would appreciate any detailed advice on what bolts to loosen and what bolts to leave alone for suspension integrity. I have my jack stands under the crossmember tube. Thanks for any advice.

Do you mean taking it off of jacks completely, back on tires? And which bolts do I loosen to give me play? Thanks for responding

no just move the stands to the jacking points on the floor pan . they are the round posts that hang down from the floorpan up front out side next to the rockers . or take a 2"x12"x 6' long peace of wood and slide it across the pan from rocker to rocker and set the wood on solid cement blocks . drop the car down on the wood . you may have to put two small blocks of wood under the rockers so the car does not rest all its weight on the center tunnel.

Thats what I was afraid of. I have alot of rust on that area of the pan by the pedals. Most of my front pan is missing in that area. It needs to be replaced too. I planed to work my way back from the front. Any other alternatives?

they should be even if the pans are rusted out . i have had to do the bord thing for that reason . you may want to level out the car by putting stands under the rear also . you will see the center tunel drops down some and needs to be blocked so it does not crush that part in .

re double flange

the "double" is the old suspension plan flange.
although i appreciate the idea of saving it for thickness,
you will probably find a lot of rust in the joint.
i did when i ground mine off during pan replacement.
and the pan will fit better.

I spent about 4 hours today grinding spot welds and edges today. I will probably end up grinding the "double flange" off for best fit. The bigger problem is still getting the suspension loose. I tried to support at jacking points with 2 jackstands under a 2x4 between the two jacking points. But when I lowered the supporting jack down to rest the weight on the 2x4 there was just too much crunching and give. I dont think it will hold without doing damage. The front floor pan is just too corroded right now. I am going to try again tomorrow with the 2 forward jacking points around where the fuel pump is. This area is much more solid, hardly any corrosion but harder to access with the jack stands. Wish me luck

BTW, i did my pan with jack stands just like your picture.
i think the pan goes in easier from the top, mine did.
but i did replace the ends of the laterals, about 6-10"

you need to rest the car on a 2x12 or a 2x16 board . you need to spread the cars weight out on the peace of wood . using a 2x4 all the weight is concentrated on a 4 inch spot so it could dent in the rockers . and don't try to put the wood on jack stands get 2 cement blocks . it works and work good doing that way .
