200-4R Behind a 340 and Reid Bellhousing Build

Tryin to keep the original console and ad a b&m shifter to it or as I read on here, adapt the original shifter. Don’t want to cut up the floor either to do it. No rust, like new. That’s the advantage to the vendors unit. I also read where a guy welded extensions to tha crossmember mount to lower the tranny. Nowvibration either. Evidently the u joint angles were close enough. No floor cutting.
