I gutted mine and threaded the holes and stuck bolts in them. Unless you are going concouse or drive a lot in very cold weather, get rid of it.

guess i should have asked that before I powdercoated them :huh: any trick to tap cast iron?

 

[Hoosier Bird]

Taps very easy.........just regular tapping fluid.....I would have done this for you......

 

[generaljmwlee]

no big deal I got taps just not sure about doing cast,didnt even think about it untill I said something about not wanting any exhaust leaks

I got tired of the put-put-put past the worn-out shaft and exhaust fumes. A 3/8-16 tap worked, didn't even need to drill the hole first.
