Yes it is. Actually it has no bell-housing so it will bolt up to what you want it to.

didn't the DIESEL T19 have a 4.19 or there bouts 1st...that deeper first is a gasser trans IIRC
Just sayin

FWIW I don't have any solid source to back this up (although my experience supports this), but I've heard that there were two diesel T-19's...the earlier trucks had one variant that was a bit closer to the g@$$er trans ratios (although 1st wasn't a granny gear), and later trucks had ratios that were closer together and closer to the 1-4 gear ratios on the ZF. I know that the T-19 that my truck originally had, 1-3 were all on the low side and there was a big gap between 3rd and 4th...3rd was pretty much wound up by 30 to 35 mph (4.10 axle), whereas 4th was almost too low. The only other T-19 truck I've driven was an '86 with 3.55 gears, and the ratios felt much different.
Certainly, not not even taking into account the extra overdrive gear (which made for a night-and-day difference on its own), swapping to the ZF on my truck made a HUGE difference in driveability...the gears are spaced closer and match the power band much better than my old T-19 did, IMHO...

The answer to all your manual transmissions gearing questions (scroll down to middle of page):
http://www.blueovaltrucks.com/tech/transmissions_manual.htm
If you compare a close ratio ZF5 (S42) to a close ratio T19 about the only difference is the ZF's OD gear, 1st thru 4th they are nearly identical, and IMHO they are hell with 3.55 gears (especially if you're loaded good, stopped on a decent hill, and there's a slick lawyer-ed-up a-hole in a fancy car mere inches from your rear bumper). With 4.10s the close ratio may work noticeably better, but with 3.55s IMHO a lower 1st gear is a must. Creeper gear may be a bit too low for most, but the 5.11 that is for sale here should work pretty nice, and if you run the numbers it's very suitable for a splitter unit too

Thanks, LCAM...I forgot to mention that my truck's an '84 (built in August '83), so the info on that page corroborates my experience pretty well. And, yeah, those ratios might work better with a gear splitter, but I contend that, without the gear splitter, they're too wide to play nicely with a diesel...and, that may well be why Ford changed the ratios...

I have to say I've been informed and learned something new....never knew there was a wide ratio for the diesel..
Thanks LCAM for that link! Good stuff...this site rocks!

Warden, I drive a creeper NP435, the gears on this one are like 1000 rpms apart and a 3-4 upshift while pulling a steep grade simply doesn't happen - she greatly dislikes shifting at over 2500rpms, a quick drop to 1500rpms in 4th is murder for 3.55 non-turbo truck. So I just wind her up in 3rd, ain't like I got a B17 propeller for a fan that I should worry about taking a flight 
I had a close-ratio T19 and for a lighter and/or lower-geared truck I think it would be great, but it just wasn't working too well at low speed under heavy load. I looked for a 5.11 T19 but at the time found none, same with the 460-specific creeper T19. Had a choice between T18 and creeper NP435, either of which has non-sync 1st that is mildly annoying but whatever, sure beats slipping the clutch. Picked the 435 cause it's got lower gears and cast-iron adapter housing (and there was a 205 hanging off its end that I got as a package deal). Based on my experience with both the close-ratio and the creeper 4-speeds I think the 5.11 would come as the happy medium, of course everyone has different preferences plus I'm shooting for a splitter eventually anyways.
