OK...so I've got myself in a pickle.

I've put a 98 Firebird dash into a 67 Firebird. The car hasn't been driven yet, it's going to paint in a couple of weeks. It has a 1227730 ecm running a hodge podge of of parts to make it go.

The dash is working...somewhat. Most of the issues can be resolved by finding and connecting the right wires. The biggest hurdle will be the odometer. The dash has a digital LED odometer which has to get information from the stock ECM...which is no longer there.

Has anyone here tried to make a swap like this into one of their cars and had a similar issue? Is there anything out there which will resolve the problem easily? There isn't much information out there on the subject. Most aftermarket digital odometers are for bicycles. Maybe one of those could be grafted in?

Any help will be greatly appreciated.
