this is just one of many ways you can have nice aftermarket knock off mud flaps for $20.
we made these for a 95 subaru impreza but these steps are universal for any car!
tools you need:
two semi truck thick plastic mud flaps - about $10 each (from peterbilt shop in WA)
ratchet and socket set
skil saw or rotory dremel tool
pencil or pen to mark you lines
can of spray paint or similar (for rounding off the edges)
Step 1: measuring and marking
measure your mud flaps on the car so you can determine how far you want yours to stick out, in our case we decided on the front having 1" more outwards and 1" longer and the back 1 1/2" wider and 1 1/2" wider
first remove the front mud flap and put it on top of the semi flap. make sure the flat side is facing down.
measure how much extra length you want and put the outside edge of your stock mud flap on that line, so you have the extra 1" of material, mark your lines. and trace the outline of the mud flap: this is where the t-square comes in handy!
dont forget to mark the mounting holes from the original mud flap
