Projects 29 Coupe B pillar length needed

I need to fab up the "foot" portion for both my B pillars on my coupe. Does anyone have the total length of a B pillar? Want to know how much I am actually missing.

 

Got a photo of the area your working with?

 

The car is completely apart. Almost every panel and post are from different cars. No floor. I do have a half decent subrail ***embly.

 

Not going to add the piece I make until I ***emble was just curious how much I was missing

 

So your needing the foot that attaches the b pillar to the subframe inside ?

 

Yep
