'98 LS 4.3 4x4
Hi guys and girls. Have to change my cat convertor (have a rattle off and on and cant find it. Strapped the heat shield to no avail) anyway i was looking at the bolts on the flanges and cant figure them out. Theres a nut on one end but the other end looks just like a smooth head on it. Havent found any like it anywhere, So my question is what can i use (size, style,etc) before i start to take everything apart? And can i get them at auto parts store? Thanks in advance.

The rounded end is pressed into the flange. You just unscrew the nuts. The studs will probably break, but they can be hammered/pressed/drilled out and replaced with "regular" 3/8" nuts and bolts.

 

Thanks for the info. Kinda figured they were pressed in.I found these on amazon. Which would you recommend i use. One is M10-1.5 x 62mm and the other is M10-1.5 x 35mm

Damn didnt realize the pics were going to be so big.

 

35mm should be plenty long.
