help with astro roof headliner

[ricks86442]

any help will be appreciated... i have a 86 442 with the astro roof option ,that the previous owner started to put a new headliner in and didnt finish... ....problem is it seems to have something missing around the astro roof opening chrome.... new headliner is about 3/16 inch short?

is there any pictures or decriptions in the chassis manual or any other book i could look at???

thanks in advance
