bad time to need an exhaust from Italy, will now need to shim my lafranconis

[amamet]

I guess my plans on a spiffy Zard exhaust for the lemans are going to be on a hold for a while.  does look pretty dire over there.  I may need to reinstall my lafranconis after some rehab on them.  the headers are 38 mm while the mufflers are 40mm. I made up shims a while ago from some scrap aluminum I had but would love something better.  any help is appreciated. also what's the best way to seal the crossover, like everyone else, no o-rings left on mine

thx
