theyre are 2 types of plugs aswell
i know some are similar to some 4ag ignitors
so maybe goto wreckers and look at them
some ignitors have tabs on each side fo the plug
some ignitors have a tab just off set across the bottom
if u loook at yr ignitor u will see what i mean
the igniters are just a pair of 4 cyl toyota igniters so you should be able to find something from your local wrecker. Try 4age levin or corolla, there are 2 different igniters they can have. Should have a number on them you can match
