I think I know the answer to this but just to confirm, don't the cross member bolts have the threads up? Otherwise you could not move the cross member with the body on?

Thanks guys

I am gonna say the bolts go up because thats the way mine is presently and I honestly believe (can't confirm) the crossmember has never been removed. In fact I even left it in place while I blasted/painted the frame. However I am missing one of the 4 bolts/nuts  Sad.

Yes!  The bolts go up from the bottom.  Threads on top.

Anyone know what these bolts are?  Thread pitch, size, finish, headmark, washer size and finish?  Thanks.

Here's a pic of an original. You can get a functional bolt w/built in washer at Ace Hardware. It won't have the head markings but will work just fine. I think it is a 3/8" x 16 x 1 1/2.

The bolts have a flanged head with the letter A and three lines.Also they take thick washers and locks on one side and only locks on the other.Very few four speed cars still have the correct bolts and washers. My original 07c 68z never had the cross member removed and this is what I found.  John Allouez Restorations

AMK has lots of those A headed bolts and I'm sure they have these.  If I have part #'s (which I can't find in the AIM) I could order from them as I'm putting together one already.  That picture looks like the tansmisson mounting bolts.  I'm looking for the crossmember ones that bolt it to the subframe.  If some one knew what size and length they were I could match them up.  I would probably need the size of the washers as well.

Those are the bolts I referenced above...


The kit includes the washers and nuts too.  Just $6.95!

No, I knew you  and John had it right, I was just referencing the picture and that it looked like the tranny bolts.  I appreciate you getting me the link for HBC, but the reason I was trying to get the part # and use AMK was I'm getting eaten allive by shipping.  I have an order to put in to AMK and to add a few bolts won't change shipping.  I ordered some motor mounts and forgot the bolts.  Bolts cost $4.00- shipping for two bolts-$9.50 and it's adding up real quick.

The bolts from AMK are not correct.They would be ok for a restored driver,but not a judged show car. Is the car going to be judged?   John Allouez Restorations

Hopefully, some day.  If AMK is not correct, are the ones HBC sells correct, or does he get them from AMK?

Crossmember bolt kit from HBC doesn't have flanged heads and are TR headmarked.
