Bench to Bucket Conversion Advice

Nice job. I still think I would use something much larger than a washer down below. Even a 4” blank electric box cover.
The chances of “needing “ it might be slim, but...
That's a great suggestion. I will revisit after I've had a little break or maybe just do it over the winter. I didn't just do the seats. I also pulled the instrument cluster to replace the performance indicator with a tach, update the cluster lighting to LEDs, and installed a Retrosound stereo/speaker in place of the stock radio/speaker. So I've had enough of being folded like a pretzel for a bit lol.
