I want to try some different mufflers on my blazer, It would be easier for me to order the right size flange to weld onto the muffler so i can bolt up to the exhaust pipe.........

can someone give me the dimensions on the two bolt flange.......[bolt hole centers and exhaust size]......

will this work??

If the sizes vary in years of blazer.......then i'll just have to unbolt the flange and measure......I didn't want to do that until i could order new flange and gasket, because I'm sure that the gasket would disintegrate , then I'd have a leak until i got parts........
