Banjo fitting size?
I just put some mini apes on my 2004 Road Glide, and found I need to extend the brake line. I'm going to use stainless line, with a aftermarket triple fitting.
Does my Road Glide have 10mm or 12mm Banjo fittings at the master cylinder and calipers?

Harley-Davidson Banjo Bolt Thread Pitches
Prior to 2004, there were only two thread pitches for EVO / TC88 models. They were 3/8-24, commonly known as 10mm, and 7/16-24, commonly known as 12mm. (12mm is symbolic only, actual bore size is 11.2mm) All single line front models used a 7/16-24 thread on the master cylinder. 3/8-24 thread bolts are used everywhere else on all models through 2003.
With the introduction of the 2004 XLH (Sportster) models things have now changed. XL883, XL883C, and XL1200C models use 10mm x 1.25thread on both the front and rear master cylinders and calipers. The XL1200R uses a 12mm x 1.5 thread on the front master cylinder and 10mm x 1.25 on the rear master cylinder, and front and rear calipers. Only 2004-2006 models use true metric bolts. All other models have not changed, see paragraph 1.
To eliminate confusion when assisting a customer make sure what model he needs bolts for. Use paragraph 1 for all EVO / TC88 models except the 2004-2006 XLH models. Use paragraph 2 for all 2004-2006 XLH models. If it is for a custom bike 3/8-24 will usually be the correct choice.
I think this information is correct but a bit incomplete. They don't mention the Touring bikes with a dual caliper set-up on the front. If I'm not maistaken they use a 3/8-24 bolt in the master cylinder.
