This is an excellent thread, bolters putting their heads together to figure it out.
Yes I agree you get things done with greater Numbers. Knowing its ether a 37/38 is ok with me, not knowing its ether a Chevy or GMC not a real big deal as its still a GM product.
And I say it again THANKS so much for what little to little more I have learned for this FORUM and its participants, kudos to you all.
