Got one vacuum nipple installed then things went sideways... This is a 5mm x 0.8mm thread with a 1/16" hole into the bore.... Need to take the other one to the machine shop to get done with better tools. Someone on Facebook finally gave me the measurement of 2.75" for the dipstick tube. Cut it, installed it and with 4 quarts of oil in the pan read exactly full! AMK makes nice motor mount bolts with attached washers. On the LCA don't tighten those nuts till after you have the torsion bars adjusted up. Laid out the exhaust and it is very close so I finished up the collector.... I have no idea if I can get those pipe out now they are connected.... I hope I never have to. The driveshaft is restored with NOS parts and my custom exhaust is very close to matching the factory exhaust... minimal work to get it connected to the Accurate Exhaust 2.25" center pipe after the power train is installed.
