Radiator Insulator Kit (Top & Bottom)


Reproduction Radiator Insulators as used by Buick

Fits 1970 – 1972 Skylark, GS & GSX

These replicate GM Part #’s 1387422 & 1387423


These are currently SOLD OUT!



Note:  These are the BEST Reproductions on the market for our Buick’s however depending on the size of your Radiator you may need to grind out a portion of one end to fit your Radiator.

This is easily accomplished with a simple bench grinder. At this time nobody reproduces a bigger size for 4 Core Radiators. May be hit or miss with an aftermarket 3 Core Radiator also.
