I have an 80 mirada cmx that i bought from my aunt when my uncle passed away.It has 79000 miles and sat in a building since 1994.I've went through the brakes and fuel system and it runs great.The quarter extensions were shot as usual so I bought a set from replica plastics,only to get dissappointed on what i got. I trial fitted them today and they are garbage,a half inch to short to the bottoms of the rockers,warped,cracked junk.Is this the olny options we have?thanks
