What other dual point distributor besides the IBS 4003
would just drop into a 58 poly.
Can a 58 single Point distributor be converted to dual points (how)

Yes, you can convert any of the old single point distributors to dual point by swapping out the guts from another dual point iron distributor. I have some that I would sell, if you are interested. However, I don't do this with my own cars. Instead, I install a later electronic distributor and run an HEI ignition module attached to the bottom of it. These will drop right into a poly engine without requiring any modifications. You can read about that here: http://www.designed2drive.com

Also, you asked about other dual point distributors that will drop into a poly. Any of the early 241 or 270 Dodge hemi distributors will drop into a poly. I have some of those to sell, if interested.

I have a Sun 680 distributor machine if you want to set it properly and throw a curve on it. I'm located in central Jersey.

Any A & LA dizzy will bolt in. You want OEM look? If so swap guts as mentioned, if not get one for a 340, original of aftermarket.
