Just went and got some quick and dirty measurments from the garage.
Presumed original subframe - both sides around 7mm thick.
Pattern Subframe - around 10mm (can only get to one side without dragging half the garage out).
Stub length - just over an inch.
Looks like I will have to deal with this in the future too....
Hi Rusty,
Thanks again for your measurements. Just to update you as I believe you have a pattern subframe, I fitted a plain washer and new grade 8 zinc plated nuts on each side with loctite and it all pulled together nicely. The bolt now is now just protruding through the nut.
Cheers guys.
Nice one, glad you got it sorted out.
I'm still a way off fitting mine, but I appreciate you letting me know what to expect and how to overcome it!
