I mentioned these spacers in another thread about factory rear swaybar spacers, and just added the third pair today in the front holes.
My solution- 1" round aluminum, 1-1/4" long, 7/16" hole. I'm using a Blazer rear bar currently so M10 x 60 mm bolts (70-80mm? with factory bar), nuts, washers. 3/8" bolts would work too. There are actually six holes in factory control arms, so you could make six pieces and stiffen the arms a little at the front hole location also. Also notice the zip ties to keep the E-brake cable from rubbing the inside of my 17x9 rims. Fancy-eh?

I mentioned in the "What did you do to your G body today" thread about turning over 90k miles and developing a miss on the same day. Life has slowed down my troubleshooting, but after swapping the distributor, plugs, confirming plug wires, and so forth, I have come to the conclusion that my camshaft is toast. I had the Lunati waiting, so it begins:

Only 24 days or so until Hot Rod Power Tour- no worries, right?

#8 cylinder was dead, and the exhaust valve pushrod was a little loose in the tear down picture last post, so I assumed the cam had a bad lobe. Pulled V/C's, valvetrain, and cam, and much to my surprise- the cam looked OK?? It had two lifters that weren't rotating, and one with some spalling/pitting, but #8 looked good. A little coarse language and further investigation revealed #8 exhaust valve spring is broken. Ordered new springs and retainers. Hopefully they're here by the time I get everything cleaned up and ready to assemble.

Crazy, usually it is a flat cam, especially from those years of the sbc 305. New springs to match the cam along with new valve seals is a good idea anyway. Nice car by the way👍

Yeah, the broken spring from this era is a new one for me. It's not like the LG4 cam would rev high enough to hurt anything. I wouldn't be surprised if a 3hp Briggs&Stratton had more lift and duration.

First time looking in, car looks great! Beginning to really like the early Cutlass styling.
