|29/01/2006 14:28:27||John Wood (Woody)||Hi Ian, on V4s I have done some patching mainly repairs to front apron,replaced two, rally reinforcing of turrets and cutting out and rebuilding the side panel under the steering arm holes where the brake pipe fixes. Have also replaced the boot floor. The front engine floor is quite thick, especially at the side of the gearbox where I cut the holes for the rally exhaust, and any repairs are best done with an empty bay as it is easier to weld from above. Hate welding upside down. Has the floor rotted up to the joint with the bulkhead? If you do have to work underneath make sure the car is as far off the ground as you can and also you have to remove as much underseal as possible as it burns. I can visualise a suitable triangular support for the floor to bulkhead, but if the repair pieces are thick enough it may not be necessary.|

To be honest I would repair the area by cutting all of the rot out and welding in new material. Its quite over engineered for the two stroke, so as long as you do a good job there should be no problem.

If you are able to cut out the old and weld in new then that will be easier. But you will end up doing it from underneath. You have to guard against weld splatter against transmission boots, and steering bellows. Whipping the engine/box out might seem a chore, but you will have a clear working area and better ability to see if there is any other areas that might need attention.|
