Hi David.
Yes. Thanks. For sure.
I'll be bracing exhaust system from muffler to Driver and Pass. side
of engine. Lot's of threaded holes on Driver side of block, not so
sure where to mount from pass side. Maybe I'll do it from from bottom
of accessory bracket. (No PS pump there.)
Is using a flex joint in exhaust system a bad idea?
I'm kind of modeling mine after this design (Tiico I think):

Thanks,
Neil.
