They have been chemically washed, burred to rough up all faces and finally alcohol cleaned before being completely filled and left for a week in warm conditions to cure.
You can have them individually for £15 each delivered.
The passenger mount has been cut off and a 3mm plate welded over and all glued back together


Gearbox mount, bracket not included as its a waste on postage


Rear mount


Front mount


They are more suited to track cars due to the added vibarations, but the fronts are recommended when fitting any stainless manifold to take the stress out of the flexi from to much movement.
