George,
It's for a 1 1/8 or a 1 1/16" input shaft. Not sure what you mean about the forks. Are you referencing how tall the TO bearining is? If so I believe it is 1.5" but I can double check that when I get home tomorrow night and let you know. I'll be more than happy to mic each measurement as well when I get home. It's a 1 1/16" TO bearing. Which ironically enough measures larger in the ID than a 1 1/8".
Roger,
Not sure, You'll have to tell me as I don't know what fitting you need, The fitting is a -6AN (M) to 3/8NPT (M). If it works, lets call it $5 and I'll ship it to you either Sat/Mon. Just paypal
