Thanks nickh75, for your reply, finally sussed it, the threaded stud on Monroe gas shock's are shorter by 15mm, if you use OE shock's, no problem with Flo-Flex Polybushes, and after speaking to Flo-Flex can cut to fit, so out with the bandsaw, trimmed 4mm, now all fitted, the ride is very firm, just great.
