Hi everyone, I'm getting ready to pull my 250 out of my 73 Comet. I've probably asked about this before but it's been awhile. Are the brackets mounted one in front of the engine and the one in the rear with the obvious holes in them to lift the engine strong enough? I'm assuming that's why they are there, but made pretty thin, also the bolts aren't too long that mount them. Was going to pull engine and trans together so concerned about weight. Thank you everyone.
