Side rail mounting repair

After fitting a new battery box I found the rear side rail mounts on the rear tub were corroded and unsafe. I needed a new rear mounting!!! For the previous MOT I had bolted a 3mm alloy plate on the under surface of the rear tub to bolt the seat belt reel bracket to. To mount the rear side rail I needed a bracket to hang down inline with the rear tub original mounting points. I found an old seat belt reel mounting bracket and welded side gussets to give additional strength. This was positioned to hang behind the side rail mounting points and the tub drilled above through the plate reinforcing the reel mounting. The side rail mounting holes were marked off on the new bracket before removing it for drilling. To tidy up the door side of the new mounting I made an aluminium plate held in place using the lower seat belt bracket mounting bolts. All finished brackets were painted and wrapped with denso tape. All that was left was to replace the battery. This was done using plywood with a hole cut out of battery footprint . This was cut in two halves and positioned in the battery box. Two eye bolts were made to bolt through the plywood and battery box base. Finally a ratchet strap was used to hold the battery in place.
