Motor mount question.

[andrewt2]

Ok so i think im dealing with stupid people at my local parts store. i go in today ask them for a set of motor mounts and a trans mount for my 69 stepside they tell me they aint got access to them. so i come home, type up advance online. and i find this...

is this the right motor mount needed for my sbc? if so im going to be extremely ticked at my parts guys because it shows they have one in stock at the local advance.... just lazyness on the part of the counter help not wanting to look it up in the book since his computer didnt go that far back...
