Took the car down today to get the seats put on the stock runners and have the rear struts braced.
He is going to take a pattern from my front strut brace and anyone who wants them can then order one.
The rear strut brace is being welded in and is being triangulated for further strength. Not sure if he is going to pattern this as a bolt in part also (I will ask)
On the seat runners he stated that there are so many variations on seats and mounting points that he would need the car and seats to sort anyone else's, but said it wasn't a problem to do.
