I bought (and ruined) two sets - one from JC and another one from a local supplier.
I finally bought a set from bowtie_bits on eBay and it fit perfectly. I modified the installation procedure slightly from what I read in the tech tips and it went in beautifully within about 2 minutes. I know we are not supposed to endorse a supplier here but, this head liner is absolutely the best repro I have come across. Supposedly made in America from the original dies.
