1970 340 swinger headliner installation question

I agree with the above comments. I did mine my self but wouldn’t recommend it unless your READY for the job.It takes quite a bit to get it right..!! After doing mine, to get it done nicely I wouldn’t consider 750-1000 to be out of line. Not including the headliner. This was in a 71 swinger. Standard 5 bow stock replacement. Yes my front rear glass were already out. Good luck no matter how you go about it…Swingn’
