I just took the battery tray off my car and put one of the reproduction ones on, but this one is still very solid and good for a driver car--$10 Will ship in a USPS large flat rate box.
Coolant control valve was NOS when I put it on my car 10 years ago, but it is technically not the correct style for a 65--this one is for a 68 and newer GM car. Works perfectly on a 65 GS though if you are not worried about having the 100% correct appearing part. Bracket has been opened up for it to fit, so it includes the bracket--$25 Will ship in a USPS medium flat rate box.
Rubber isolators that go above and below the radiator. You can get them new from Steele rubber for $80 a set! These still fit and function fine, so if you don't have $80 to invest in a new set, you can have these for $10 Will ship in a USPS small flat rate box.
