If you go with the 1973 Blazer heater blower up grade and you have to resize the hole in the fire wall for it to fit. Find a Electrial Contractor and got him or her to use a Hydraulic Knock out to re cut the hole. Rob aka PASmokeater brought one home from work and in a min or so we cut the fines 3.5" hole ever seen. Just a tid bit on that project. Tug :wink:
