Front fork leak FLSTC

Front fork leak FLSTC
Hi, Dang it, my right front fork is dripping oil from bolt at bottom of fork.
Assume I need to replace fork seals?
No oil on entire length of fork, just on bottom bolt, the left (rear) one.
Very slow leak, a fifth of a teaspoon puddled on rim after 2 weeks sitting.
Clean golden oil I replaced a few hundred miles ago, see & touch on bolt.
Both bolts were already tight; I didn't touch them when I changed oil.
No leak around fork oil drain screw.
Indie quoted $360 labor, $40 parts. Will do myself if needed.
Softail Heritage FLSTC 1999, 42,000 miles, still pretty.
Thanks! Kayakeur Bud

Personally I'd just try tightening up the bolt first.
If that doesn't work just take out the bolt and change the crush washer and reinstall the bolt.
You will need an impact to remove the bolt.
Not to mention that you will have to take out the fork spring before removing the bolt as well.
It's a 6mm allen head bolt.
You don't need a long shank 6mm allen to reach that bolt but you will if you ever have to tackle the one on the left.

Guys, I think I mis-stated the problem, the location of problem.
photos below
Leak oil dripping from
Actually not from bolts but a pair of nuts at the bottom of the front fork/shock.
There is no oil drip path down the length of the fork, no oil collected along lower rim of wider-diameter cover (I guess #44, p/n 45964-86 ).
No oil seep from drain screw #29, pn 45858-77 (I changed fork oil a month ago, did not replace the copper washer)
Parts Catalog diagram pages 72, 73, 74, 75.
Nut #14 p/n 7748W
onto stud #45 p/n 45998-73
through #24 axle cap 45832-77A
into #36 slider p/n 45917-86
Tried tightening the nut but it was already on so smug it didn’t move with my best estimate of appropriate strong torque.
Tightened the drain screw teensy bit, measuring torque with the meter inside my fingers, dared not torque it more.

You have to take the axle off to get at the bolts I am talking about.
It's part number 17 on the exploded diagram for the '99 Heritage.
