engine crossmember bolts

2nd 66 · Nov 16, 2015

I'm trying fix fix some of the hacks that the previous owner did ,The drivers side engine cross member bolt has been broken since I've had the car 15ish:shrug: years the cross member was moved slightly forward and held in with a 3/8 self tapping screw .I got the broken bolt drilled out albeit slightly off center tried using a screw extractor with no luck .So the way I see it I have 2 chances first is getting a drill and tap combo http://www.homedepot.com/p/DEWALT-27-64-in-Drill-and-1-2-in-x-13-NC-Tap-Set-DWA1416/204787201 and if that doesn't work finding the elusive 17/32 drill and trying a heli coil
Will somebody confirm the bolt as 1/2 x 13

If you can get another bigger bit into the bolt, it should collapse around the bit and you can reverse it out. Dose that make sense? Just large enough not to hit the inside threads but large enough to get most of the bolt material out from the bolt threads.

yeah I get what your saying ,but the bolt extractor I was trying to use should of done the same thing if it was going to work:shrug:

FIXED using this
DEWALT 27/64 in. Drill and 1/2 in. x 13 NC Tap Set-DWA1416 - The Home Depot
Now hopefully the other side will come out without issue and I'll get a pair of those special bolts

FWIW. Make sure you have the correct cross member. The difference between my 65 and 69 is not much and easy to see how cross threading the wrong one into place could happen. Brian
