LS6 Chevelle inner fenders

[Mr70]

This is so tachless, but I'd Leave it the way Chevrolet built it.

The fiber fender skirts were actually made first for the new 1970 Monte Carlos,because it had the longest/heaviest hood (6' feet),among all the other cars in it's fleet at that time.They were also designed to help with road rock noise and help buffer the engine compartment too on the elegant luxurious M/C.
Chevrolet liked this idea,and continued with it on other cars.
Before this,they offered a Steel skirt coated with an added optional sound deadner,which went by part #3975419-20,that was supposed to do the same thing,but wasn't well received.
Arlington Tx. was a New A-body plant beginning in January 1970,so for some reason they were shipped more of these fiber fender skirts then anyother plant for 1970 production it seems to me.
I think that plants used up what they had already,so some vehicles received a fiber on one side,and a metal on the other,if supply deemed it.
Other plants got them later on,but it seems R cars got the lions share for 1970 vehicles built.
By the 1971-72 & up years,these fiber skirts became standard material on all cars at all plants.
