I broke off a hatch pin, and two easy outs trying ot extract it. It appears my best bet now is to remove the entire holder, BUT I'm worried about stripping / breaking the bolts.

I have tried to douse them with PB Blaster, but I fear gravity is working against me. Is there any way I can drill into the aluminium housing to get the bolts closer ot where they go into the frame to get some blaster there ?

I'm willign ot sacrifice the bracket, but I don't want to strip the bolts, and given how tough the pin has been it doesn't bode well.

Any suggestions woudl be appreciated.

 

In mine they used philips screws out there. Those are easy to strip at the "plus" grove. I used a Dremel style cut-off wheel to cut a slot for a flat screwdriver. Also used a small ratched and an adapter for better leverage while unscrewing it.
Unfortunately this solution doesn't address the possibility of breaking the screws completely...
