I also added flange bolts but I don’t recall the size. They take a 15mm ratchet wrench (the only tool I use for the job now)…you can crank them off using your left hand as leverage.

Yep,I bought some m10 1.50 flange bolts from ace ,could easily get a 15 mm wrench on all of them,cats looked great,my number one exaust valve was hanging up in it’s guide so I ended up replacing the 2002 cylinder head with a tupy and now it runs great.pro tip getting the intake and exhaust manifolds are a breeze with the cats out of the way!
