The shaft rockers on my LS3 swapped '81 Camaro required taller valve covers and my tall COMP LS covers are hitting the huge wiper motor. Has anyone found a slimmer wiper motor? I see that Detroit Speed has a "Selectra-Speed" unit, but it is not listed for '81; only through '78. I also see that RainGear makes a completely hidden kit, but the price of $600 is rather high and it requires changes to the dash to replace the GM wiper switch. Any other suggestions? Thanks.
