French Bass Brace advice

[Adrian Levi]

Here are a couple of pics. The centre join had a piece of epoxied wood in it up to the big brace as can be seen in the pics. The back sits perfectly on the ribs now after I took it off (before it was being pulled in all directions from the epoxy).
Now what route to take.... full center seam inlay ???
Due to massive peer pressure I will replace the back brace .
Any advice on how many braces the bass will need , Im guessing 3 or will sturdy patches along the centre seam be an option ...?
