    First, Why the silly star pattern head?

    Mine won't come loose, tried soaking with Seafoam Deep Creep, heat, and broke a T-45. I also used several finer words & phrases of the English language.:eek1:

    Looks like I'm gonna have to cut & grind from underneath:rolleyes: So if I replace with grade 8 hardware they should be fine right?

    I am no expert , but would think grade 8 is too much . get a big boy in the backseat and maybe it wil break instead of stretching like a grade 5 :wink1:

    there is a torx socket that is called "heavy duty removal" and the design of the head-edges is different to aid in removal of stubborn bolts...

    T45 is the wrong size for one thing.

    There's a reason they make a T47 :)

    I've busted a T47 off before, but it was a parts store cheapy. As to the reason they used the goofy sized torx, probably to try and keep people from actually removing the seatbelts, like the later anti-tamper torx holding the K5 top on.

    Well, I've heard others be darn sure they were T45 as well.

    I don't know if you can cram one in there, but I know for a fact that the GM tool used in 1986 for the C/K series seat belt was a T47. It's in the manual. Not saying they didn't jump around, early on with the Torx they may have been a now common torx size, then the invention of the T47...

    A T-47:doah::(

    All I've found is T-45 and T-50.

    Haven't looked in a tool store yet, just franchise auto parts stores. Broke the no-name and the second one is a Lisle (sp?) It bent:mad:

    Maybe it is a T-50 I'm talking about. I do know I bought the wrong size at first and returned it for the one that broke.

    I actually looked at this thread before taking out my seatbelts to remove old carpet and was unable to find a T47 as well, so i just bought the set hoping one would fit and the T50 fit snug. They probably changed something along the way.

    I did some research on this and Dorian is absoultely right its a T47. I would imagine if they were'nt tight you could get it out with a T45 as well thats probably why people think this is the right size, as for the T50 if you go to you local sears my craftsman fit fine. There probably close enough in size thats why the T50 fit.

    I've found T47's at Schucks/Checker/Kragen individually, (cheapies of course, but usually work) but more often than not you'll see them in a set.

    Screw 'Em:mad::mad1::mad::mad1:

    The:hack::grind: It is!

    So back to hardware. #8? Can anyone suggest a low profile head other than a carriage bolt? Those are stupid too!:rolleyes:

    Are they button head cap screws? (not sure on the name, that just popped into my head) I know there are allan headed bolts that look like a carriage bolt. If you hate trying to pull torx though, I'd hate to try and remove an allan stuck just as tight.

    Maybe a stud just the right length, and a nut with a built in washer. Those seem to be a bit more low profile than a standard nut. Only things I can think of.

    I had the same problem. Broke two torx bits. I ened up grinding out the bolt head from the top :grind:, and then punching them out. Much more comfortable inside then underneath.

    I'll go from underneath because I've pulled everything off the frame but the body:D I'd pull the body but there isn't any space left to put it:doah:

    It's a T47. Snap-on makes a "special" torx just for the seat belt style bolts with a wider gripping edge just to get these stubborn bolts out.

    8 is fine and you can get button head bolts but they will be allen head.
