I am planning to weld my spider gears. I am going to follow the directions on http://www.off-road.com/chevy for instaling a detroit exactly. Except I am going to have the spider gears welded instead of installing detroit. Is there anything else I need to do or just follow the directions on that site exactly? I was talking to another CK5 member and he said I needed to check the gear pattern before I take everything out and check it again after I put everything back in. Is this true or is it not really that necessary? Thanks!
