[DeTomaso] Rear Wheel house rust repair advice needed ..

[andriykoisg at yahoo.ca]

The holes I had drilled, back in 1995 were 3/8 inch diameter.  They are in the same place Mike Drew recommends.
 
I am not in a big rush.  I am in the process of redoing my engine bay prior to the install of a new engine.  So a quality replacement part would interest me.  The question remains is how much should I replace?
 
I have thoroughly checked the engine bay and there is no noticable "thinness of metal" in the inner wheel house opposite to the U channels or flat section between them.
 
As I say, the only noticable area is about one square inch in the rearmost passenger U-channel on the outer face (wheel well side) just at the direction changes from down to down & in.
 
On the other hand, the amount of exfoliated rust I got out of the 3 holes was about  the equivalent of a rusted panel 1/2 sq.ft to 1 sq.ft.
 
The issue then is how much do I repair.  The more I remove, the more the work to replace the metal.  But, I need a solid repair.  
 
I am grateful for your advice because of your experience.  That is exactly what I need.
 
B.G.

So, I shooved a foot long wire and then a screwdriver into the previously drilled drain holes to dislodge any rust. WOW I got quite a pile of exfoliated rust powder and flakes. I was shocked.


That tells me your drain holes were probably inadequate.  I make them 1/2 inch in diameter, and drill three of them (one in each of the tubes, as close to the bottom as possible, and one on the flat metal panel in between them).
