The two front bolts should be easy. The rear two a little harder to find as they are a weird oversize job. I could take pictures and give you the sizes, if that'd help. Don't really want to part with the bolts I have as one day it might have to go back to std. Just let me know.
I have the two rear ones i think,they measure 20mm across the head then a 2mm shoulder approx 15mm across,total length 25mm with a 13mm threaded section ?
