I am welding in the inner suspension ear and I am trying to figure out what dimensions have to be exact and which can be accommodated in the regular suspension adjustment. I will of course try to get it perfect but I am looking for any gotchas that I have not thought about yet.
I know I should have jigged it up before I got started but that was years ago and that ship has sailed. If you have any thoughts on how to build a jig and do it now I'm all ears but I have not been able to figure out a truly reliable method yet. Thanks, John |

Jeff, how much different can you be front to back? I'm off about 3/16.
The spread between the consoles is dead on at 33.5. How much front to back adjustment do we have? Can the 3/16 be adjusted out. |

QUOTE(cary @ Oct 31 2014, 08:12 PM)  Jeff, how much different can you be front to back? I'm off about 3/16. The spread between the consoles is dead on at 33.5. How much front to back adjustment do we have? Can the 3/16 be adjusted out. If the spread between the consoles is 33.5 check the height on each side. They should be close. You can do a simple plumb measure from the ground up to the bolt hole. Assuming motor is out measure from the hole at the center upper firewall just below the window ledge. If this measures equal and the ground measurement is off you probably have a minor twist in the tub. 3/16 is not a big deal since the tolerances are loose on these cars. Personally I would be satisfied with only 3/16. I have seen a half dozen 74-75 tubs that the wheelbase is off by half an inch or more from one side compared to the other. None of these were ever hit. One was so far off it was visually noticeable by looking at how the rear wheel sat in the wheel opening. |
