I think he refers to the short ones fastening the cover on, the side ones? Can't quite remember now. They are in the trunk, avoiding the elements, the 10mm ones. Anyway, no matter, replace or not, just don't lose them if reusing, which is what I did.

I was able to unhook the tailpipe from the rubber donut and move the entire unit to the side, enough to access the long bolt.

Unless you lose them (or one) they can be reused. They aren't on tight and come off easily, clean and use again is fine. But, if you're ordering the long ones, may as well I suppose.

That's a decent price, though there is shipping. I think I paid close to twice that at local dealer, regretting immediately that I hadn't sourced from local hardware, etc. My local dealership charges retail for everything, crazy expensive.

Sent you a PM.

Second the distinct possibility of an air leak at the intake manifold, ie the gasket. It can tear most easily in the upper right corner when replaced, I believe around the upper stud located there, but that is from memory. If it was running fine before taking on this job you will need to retrace you...

Thanks. Yes, might not be a miraculous improvement adding a rear bar. Have a strut bar also ( I realize the controversy) but hoping the combination, strut bar and rear sway will make for an improvement. Not a huge investment if I find a used rear bar, or even go for a new one from Volvo. Haven't spe...
