once again i spoke with out knowing the facts
i know the early sbc 265 and 283 v8 did not have the side mounts cast into the block
i googled 58 235 and yes they do have the side mount boss cast into the block, all the back to 50 on the I6
your motor may be the original
as far as cost?
the mounts like parkwood has in that task force truck should be free if you have any 10 ga plate laying around
even if you had to buy everything it couldn't cost more than $10
this is why i fab/make everything
early sbc without the motor mount boss
58-62 235 I6 from stoveboltengine.com
