Only thing to watch for is if the fork is the older one then it will have no ODS and a one piece elastomer. The Girvin 1s where the ones with the welded steel stem rather than the alloy mount. If you put a spring on them then they turn into a pogo stick as they had no form of damping other than the elastomer and the mud in the bushings. So if it's one of those then you may need a large washer to sit between the two new elastomers to make it work proper like.
