FWIW

Not saying RB is bad in any way, but I had a similar issue with an B&B engine builder. He told me he'd "fix" it too, issued a crate pickup - I was out of the money I paid for the engine and the engine as well. Stupid me left some valuable early b body A/C brackets/pulleys on it too! Not to mention I was out of attorney/court costs too! I feel your pain and hopefully he makes it right with you!

Keep us posted.
