Is there something wron with my eyes?? I cant find any info on the chassis plate drawings giving the metal thicknesses?????

You just bash some numbers into the frame in a couple of points, maybe the 1/4" gusset on the lower front wishbone and something easier to see, in my case this is a small plate stamped and rivited to the bulkhead.

i don't think he means that

don't quote me, but 3 or 5mm seems the norm

My copy of Chris's book shows all the thickness's.....eg. page 175 top right...Chassis plate CP12, Chassis plate CP13, 3 Plate.....3 is the thickness
