I have a 1966 Buick Skylark that ive been in the process of restoring,
while installing a new Y-Pipe the exhuast mainfold cracked. It cracked
by the bolt hole so now it is a slot not a hole. Evertime i try to put
a bolt in it slips right out the slot. I was talking to my local
automotive machine shop and he says just mig weld the bolt it up with
steel wire! Dosent sound too promising to me. Now the manifolds have
never been removed so i dont want ot remove it and crack the bolts.
Can is be welded on the car safely and with a mig Thank You

I made a flange last summer for my neighbor's John Deere A
to fix a similar problem. Both of the bolt holes were broken
off. Without seeing what you got I can only guess you have a
similar problem. If so...

Think about using a large washer/flange that has a hole the
same diameter as the exhaust manifold outside dimensions.
Cut a slot in one side that is the same size as the outside
diameter of the manifold. You will probably have to put two
holes through it 180 degrees apart even though you really
need one.

Some crappy ASCII art showing the "clip". Holes the size of
your bolts drilled through where there is an "X". Use a
fixed font to view this too or it will look even worse than
it already is

Slip this flange over your manifold and let it rest against
what is left of your manifold flange.

The one I made was out of 1/4 inch steel plate. It worked
out really well and even look halfway decent. Sure beats
trying to change out the exhaust manifold. No welding
required. Just some drilling and sawing.
