Sportster fork

I have a sportster fork im planning to use, but im not really sure about what year its from.
The oil seels are missing, so i need new ones. But im not really sure about witsh to use.
Fork rubber washer seals for 59-70 XL or Fork seals for 71-72 FX, XLH, XLCH? How do i determine witch one that will fit?
How are the 59-70 monted, outside the leg?
The fork i have has 33mm upper legs and the lower legs are made of steel. The diameter at the bottom of the lower legs are smaller.

Hi,

To differenciate between early or late H-D made Sporty forks;

Early, 52 to 69: where the seal seats, it's one piece, like swagged out tube

Late, 70 to 72: that same location is in 2 parts, the bigger bit that holds the seal is shrunk on the leg

Once you've checked your legs, order the relevant seal.

Re: Sportster fork

Bought the Late, 70 to 72 seals. But i cant get them to seat right.
Tried pushing them inplace with a hydralic press. It seems like they are to small in diameter, the seal gets disformed and the bottom of them seams to swagge out.
How do i get them in place right?

Re: Sportster fork

The seals you bought only fit the tubes that are in 2 parts... Won't fit the earlier ones that you must have... You can thin them out on a lathe if you're patient...
