Radio Shack no longer sells parts for their scanners. You didn't specify which model scanner that you are looking to obtain these parts for. If it has a Whistler equivalent model (i.e. Radio Shack PRO-106/PRO-651 equivalent to the Whistler WS1040 or the Radio Shack PRO-668 equivalent to the Whistler WS1080) you might want to consider contacting Whistler to see if they can supply you with the part(s) that you need. Whistler has a limited selection of scanner parts/accessories listed on their website: https://whistlergroup.com/collections/scanner-accessories
