I'll try your recommendation in the next couple days. Thanks.

Is it common for the front seat's backrest arm to break inside the upholstery? Or is it bolted to the main frame and perhaps the bolt has worked loose and fallen out? I'd like to be mentally prepared for what I might find after removing the seat cushion upholstery material. Forewarned is forearmed.
