( 10" is width on suppliers Label on the fender from ....not made bu us... i just sell them )
This is the internal width measurement NOT the outside
 The width may vary as you would expect in sheet metal production from end to end
      Made Of Heavy Duty Gauge Steel ( 1.7mm ) Approximately measures a 14 & 5/8" radius

Not a full continues curve of 42 1/2" as the last part of one tends flatten out
All dimensions are approximate and may vary from the original suppliers information along with ours added

These are supplied in RAW STEEL....NO corrosion resistant finish at all and may have rust marks already mainly due to natural skin acidity from handling.Which is not a problem as all these will need blasting /sanding preparation work anyway, before any paintwork can be done
