[Healeys] disc brake caliper securing bolts

[pennell at cox.net]

Richard,

I would be hesitant to use the red if it creates such a permanent bond.  Especially since you plan to make proper repairs in less than 6 months.

Definitely go ahead and order 4 new bolts.  A few dollars is worth the peace of mind.
