This set of Collins KWM-2 /A  PM-2 Mounting Thumb Screws and Chassis Bushings, is a very high quality reproduction of the original set, which is required to mount the PM-2 "Piggy Back" power supply on the back of the KWM-2 and KWM-2A.

 This set consists of the thumb screws and bushings for each side of the radio.

Every piece is made to Collins Specifications and made with magnetic Stainless Steel.

The Chassis Bushings (included)  are required to use the thumb screws to mount the PM-2 to the KWM-2. 

 The KWM-2 and KWM-2A, all came from the factory with the Chassis punched for these bushings and nuts, but you had to buy the hardware kit with the PM-2 power supply.

  This set is essential to use the PM-2 power supply with the KWM-2.

As will most of the items I sell, they come with a satisfaction guarantee.
