g'day all. i am new to the site, and about 6months new to the world of FJ45's. recently soureced a second hand fibreglass rear cab, in new condition. only problem i have with it is the upper seat belt mount! it did not come with the mounting holes drilled, but im starting to wonder if it is 'safe' to still mount the seat-belt bracket to the pillar?? (it being fibreglass). not sure of the brand, it does seem very strong and well built. any ideas?
