Does anybody know if these 12" shocks would work? Looking for a little more compliant ride on my 1998 standard without spending a lot of money.

I have no idea if they will fit, but 12" is too short. 

They will either rub (bottom out) or be hard as a rock to avoid bottoming out.  IMHO

'97 and '98 shocks are terrible with the valving that was used.

'99-'03 std/tourer shocks have better smoother valving much better ride harshness is gone. Valving is the same as I/S '99-'01 shocks just that these shocks have the stronger springs.

stay with standard length across all models of 13". any shorter and the rear tire will hit the fender clearance for the shock tower cross-over support.  also going shorter increases the already large Trail number resulting in more of that unsteady front wheel handling at very low speeds.

Largely uninformed prejudices.  My wife's '98 has had 11 1/2 inch shocks for 80,000 miles with no rubbing.

I do not know if the Harley shocks will fit but 12 inches is not a problem.

I too had a custom standard with 11 1/2 shocks with bags and trunk. Fully loaded two up and never bottomed out

I also had 12" shocks for most of the 20+ years I owned/rode the '98 Tourer. Never a problem loaded or not.

I stand corrected.  I mis-thought 12" for 11".

Still, I wouldn't run shorter than 12.5".  And I drag parts on my 13s all the time.

LOL, Jess.  I just went to measure.  I have Progressive 13 inchers on my I-state.  My "show bike" has eleven and a half.  Ive been meaning to up the shocks on the Tourer but just haven't overcome my laziness.  Nonetheless I'd be happy to outride you on the "show bike" with the 11.5s.  I do tend to scrape hard parts occasionally but it doesn't slow me down much.   Smiley

If one has no experience with something one should not offer guesswork advice.   Wink

I have no experience running 10lbs in my tires either.  And I'd be happy to offer advice about it.

I do not know if the Harley shocks will fit but 12 inches is not a problem. 

unless one checks the upper area of the fender when the tire/wheel is removed one will never know that it rubs during certain suspension travel conditions. weight of rider/s and road conditions will come into play also and worst case conditions can cause major instability in the suspension system, possibility leading into a crash.

in my case after installing a 205/65-16 tire and new I/S shocks on my std/tourer, I had the shocks set too soft and the tire did rub that upper fender area. Once I dialed in the shocks setting, there hasn't been any more rubbing.
so not any "largely uninformed prejudices" but my own personal experience.
Enjoy.

416s (13") on my I/S, and depending on how I have the air set I can scrape - or not. Especially with a passenger aboard.

One of these days I'm going to test-fit a set of H-D air shocks to the bike as an A/B comparo and see if/how the ride changes.

You had a 205 installed.  The OP said nothing of that.  You did not have 12 inch shocks, so, no, you don't have experience with that.

My opinion of your opinion in this matter stands.

The shock length labeled(13" 12" 11" so on) is expanded length. All that counts is compressed length. All shocks have different collapse length for the same expanded length. You can get 11" shocks that have 10" compressed length or 8.99" compressed length.  Any compressed length less than 9.25 you will never be able to fix rub spots. The rear tail light has a bump inside fender that holds the back side of the light fixture that you can change.
Biggest interferences at 9.25 is the rear brake caliber that tucks under the fender, causing you to cut outside top fin off to clear under fender. The front portion of the rear fender on the right side at the swing arm also hits the swing arm at 9" compressed length.
Interferences here are on a 98 std. might be different on other models, but the compress length is what counts for rub spots. Not the labeled size.
