Radiator has a hole, Heater core is broken, reverse gear is iffy.
Radiator- I will likely get one from a modern truck in prep for the LT motor swap
Heater core- Fuhgeddaboudit! Winter is almost over and I was going to get vintage air eventually. It is bypassed for now
Reverse gear- I am going to make sure the trans fluid is okay and hopefully it will be good
I drove the blazer around the block though so that is promising.
