Came across this web site. Their examples sure look a lot like the front struts on my '89 Allante. Might be an interesting place to get some sort of group purchase. I'd love to replace the stock setup with coil-overs and adjustable struts.
I bet they aren't cheap though... http://www.carreracustom.com/cadillac.html
I haven't gotten that dreaded DIC message YET, but if and when I do I would be interested in these as well. We might need to look into these and inform the Allante masses.
