Is there enough material on the 13b rew to drill and tap the center iron to use the factory 13bt engine mount bracket? it would be nice if it did,then I would only have to think of a way to fabricate the other side

 

Yes you can tap and drill the center iron and use the passenger side bracket,mount and oil pan.
I did it on my car and i have a extra driver side mount bracket for sale if you want 2 drop a rew on a fd.
