I can vouch for this as I now own this car as a parts car. Nik Both frame rails were full of expanding foam by the way, the guy really tried to hide the rot.
Borntobe: Its unfortunate that You had to deal with this, however man when you’re getting custom work done sometimes it just doesn’t work out easy. I work on cars all day and sometimes something you did a week ago on another car that took 15 minutes ends up taking 6 hours on another car due to stubborn bolts, etc. This is why its best to do your own custom work/swaps - there really is no better way to learn then to get in there and bust some knuckles open.
