I am in the process of trying to get these reproduced for us. Talked the the original maker of thes and we think it can happen. They have no prints or dies these were made fom. So I am going to supply them with a strut they can use to do what they need to make these. Seems the little part at the end of the strut is the difficult part that GM required them to make for the glass to close. I have a NOS set of struts if anyone is interested $350.00. Sorry the price is so steep but these are like RARE.
