Technical Mk1 gearbox synchronizer

[Tiger black 176]

Hello guys...i might need some help .i have punto 75 from 94 i replaced my gearbox with 6 speed box so..recently im trying to rebuild my transmission i bought all the bearings and seals probably if i bought it rebuild it was gonna be cheaper but i wanted to do it my self. My question is .is there any difference between 3rd and 4rd gear synchros from mk1 to mk2 punto ?
Apparently the part numbers are different but i didn't notice any difference in the shape of it ...the gear assembly is the same part number only the hub and the selector have difrent part numbers with my vin it giving 7691029 ..and from 2005 punto vin number is giving 46772294 and 55234410...so please help if you can ..
