There's been someone on ebay selling "new" repro heatshields for around $85 + shipping ... not seen them for a couple of weeks but worth keeping an eye out for them .. if I see one I'll post the link here.
Bought mine a couple of months ago on Ebay from a person who makes them. Pretty good quality. I wanted to preserve my original since it was in such good shape and that is why I decided to buy this one. Fits very well but is not as heavy as the original. I do recommend it though.
Here is the email for the person. Maybe you could email them and see when they will be listing another one. I know there were two on EBay from this seller and both sold.
Here is the email address.
I just purchased one from the same person. The construction was revised to match the original double layer design so it appears about as thick as my original and it fits very good.
