Hi folks:

Here is a little tip on that infamous left side exhaust which is harder than some of the worst modern cars:

The last unit I dealt with had broken studs.

I drilled them out to 5/16 - 18 rather than 3/8. This allowed the heat riser to be snapped into place from the side after the pipe was connected and made the pipe easier to get into place.

Grade 8 5/16 bolts are plenty strong and can be had in special corrosion resisting coatings.
