I own an 86 coupe with the RPO Z51 Performance Handling Package and RPO B4M Custom CL Feature Package on the build sheet.
I understand what is in the Z51 package but cannot find out what is included in the B4M package.
Can anybody out there help me out.
Cheers
found B4P and B4Z but not B4M ???? thx dg
Thank you, I worked out that B4M gives you heated external mirrors, heated rear screen and rear view mirror with night antiglare tilt
and map reading lights.
