You need to find and Mount some soon as possible, as your frame is under alot off stress without them, i have seen frames that have startet to crack because they did not have the frame support bars in place. Some people have removed them for headder clearence. But the frame is flexing alot with out them and will brake at some point.

Regards Henrik. PS i made mine from a piece of crome water tubing in the right diameter. Press it flat in the ends and drill a hole in each end and you are good to go.

It is just 2 pieces of iron bar that mounts from just behind the front wheels and rearwards connecting the front part of the frame with the middle. There is one in each side. Its like If you imagine that you are jacking the car up at the front bumper, without the bars the whole nose is trying to bend upwards at the firewall.

When the bars are in place it cant bend. Also there are to bars in the engine compartment that supports the front from falling downwards  at the firewall If you Jack it up under the doors.

The frame is wery flexible. Try lifting the car a little in the center, and then open and shut the door.

Now try and emagine the suspension bouncing up and Down going Down the road, that makes the frame flex at the week spots like right under the firewall. The bars prevent the frame from flexing so much that metal fatigue can make it crack. And besides it also feels better driving it with bars in place.

Im not good at traking pictures and post them here i have tryed to but never Got it to work. So maybe someone Else here can find a pictures that shows how they mount.

Regards henrik
