I was gutted when i found my soild as a rock and never welded saph needed some new metal putting back into her.
The main place was the gear tunnel!! very strange place for it to go but as you can see if its cut right out and put back neatly you would never know!! i ended up doing both front floor pans and seat mounts as well!!!!
ive seen some lovely saphs and when u lift the carpet they have plates stuck over the top of rot!!!!!!!!!!!!
O/s gear tunnel

N/s

Ive now got to cover it all back over with sound deadining any way so you wont see it but i no that its been done to the best of my ability
