Could you share the end file?
Sorry for long time, holidays and life slowed me down. Here's three formats: Inventor (where part originated), STEP, and STL. Hopefully one format works for you.
I needed to rename the files to get them to upload, swap the .zip extensions with the caps letters in the name to get the formats tagged correctly.
For example, rename bronco_windshieldSTP.zip to bronco_windshield.stp
We mirrored the part to get the other side.
Let me know if these don't work and we'll find another way to get them to you.
