Last time we are likely to see this air cleaner and whats under it.
The old leaky Rochester Model B...been on there a long time.
Like Mr. Langdon said, gotta match the transdapt adapter slots to the Weber holes.
A file in a drill is a poor mans mill...just a kiss to make a whisker of room for each of the bolts that fasten carb to adapter.
Now the adapter is fitting the carb right.
Chevy linkage attached to the carb, make yer own linkage ready to modify beside it...raising the carb on an adapter so need a longer link.
It don't have to get cherry red, plenty hot will get it maliable enough to bend w/o breaking...a quench will reharden good steel.
Bring whatcha got in my shop, a rod bender made of pipe, vice grips and a rifle reloading press....
