No answer on the other thread I take it, if you can wait until tomorrow I can go out and take one of them out and give you a measure, Id bring it to a engineering place and just hand them the bolt and ask them if they do it in xxx mm, worked the last time I needed a bolt (amazing). Go past there from time to time so if you want me to pick you up 4 I could and post them. Possibly cheaper to sort out yourself
yeah nothing on the other thread, got the impression no one was reading it.
might be a plan, am happy to pay for them, haven't got anyone near me to take it to. and need the bolt in the engine so i can drive there
also out of interest, how far do the bolts go into the plenum?
i suppose if they are too long i can cut them down
