[88Stanger]

Ok, so i am getting the new harmonic balancer painted today, then install Friday along with the new Mcleod clutch, also i had a set of Tri-y stainless headers for my "69 i bought some time ago but then went with LS so i thought what are the odds they fit the "66, and they seem to just fine, so now i need to get an exhaust kit. The headers have this wierd ball or partial ball end where you mount up to exhaust, so i need to find out what that is called and get the connector for that.
Then i will be checking the engine and tranny angle mount along with the differential angle. I have read all kinds of articals on this and if i am not mistaken, the engine/tranny can be pointed down up to 3 degrees and the rear diff up at 3 degrees, or less for both, as long as they are not a direct line to each other, so that the u-joints must work, correct? I assume i would want to measure at some point where i think the airbags would be at ride height or ?
