Anyone know what size bolts I'll need this weekend to fasten my Sierra steering column to it's new fixings?

It's the ones for the holes arrowed that I need, thanks.

8mm with huge washers

I'm sure it's 10 or 12mm (I'll look tonight).

Conrod's right about the washers - they're about 25 - 30mm dia and about 3 or 4 mm thick.

Note that whatever the bolt size is, it's a fair bit smaller than the hole. I believe the idea is to do it up tight (hence the thick washers). In the event of a bad smash the steering column can slip in the over-size holes and start the collapsing process.

Fortunately I retained the original bolts and they are M10 (smug grin). You also need to retain the bushes though which I didn't (not so smug). However you can use the spacers from the seat belt anchors which are the right OD and ID (but a tad long) so they need cutting back about 5 mm then it all fits. Fortunately I retained these (smug again).

You'll also need new M10 nuts and four large washers of cause.

I can provide a pic if need be.
