Geof,
I have the same issue you had. I have a 69 Impala SS427 4 speed with console. The Muncie shifter is probably beyond rebuild and would like to change over to a Hurst shifter and would like to know what part numbers to order or a number to call at Hurst for advise. Thanks for any info. if you need my email, it is bobamja@yahoo.com. Again thanks!
