I also bought a couple headliners from two of the major suppliers and neither of them fit to my liking.
I finally bought a liner from bowtiebits.com it was a near perfect fit.
Might be worth another try.
I am also interested in hearing about the fit of the Bowtie Bits headliner.
I also wish they made a Suburban set.
I bought the headliner for my 46 from Bowtie Bits and it was perfectly sized. I have nothing to compare it to but I would but from them again for sure.
