Did this on 1990 Montero- Left hand drill bits- Drill center out and slowly go larger- When gets real thin- use a pick and usually piece will just spin right out- I couldn't really see into hole except with mirrior and cell phone camera- I would start working- take a picture and email it to myself and look at it blown up. May just screw out with first drill-due to Left handed bit. How many miles were on truck?
