This old posting dealt with me fabricating blocks to raise the passenger side seat in my 2019 Toyota.
At the time, there was no dealer supplied or after-market products available… The original seat bolts were too short for the added height, I ordered replacements bolts (Grade 8) from Fastenal. Afterwards, she did not feel like Lily Tomlin’s little girl character “Edith Ann” who sits in an oversize chair anymore…
