What's the labour time to replace an entire Wrangler chassis?

Thanks very much for your interest.
Addiotional infos:
for example last year I went to my jeep dealer for a recall,
there was a well known issue with the emergency brake pedal. When the job was done I received a document with the invoice on

which the problem was described, how to replace step-by-step, part number and exact timing. I mean, every part has a code and a

timing. On professionals programs every part is catalogued and labeled, with cost, number, and time. My problem is i'm not in the

us and here in italy my car is not an ordinary car, so mechanics and other have few infos, and the less for an almost 20 year old

vehicle. For commercial vechicles and other cars this timings are present (maybe i'll use one for a similar car).
I wonder what is the this time for the frame, as the manuals consider the frame like others parts.
(i see many sell it for restauration pourposes too).
I know it's a crazy request, and nobody sane mechanic, professional nor bodyshop will afford a job so long and expensive.
I need this info for a simple reason, I had a road accident.
And I need to estimate repair costs for have the insurance refund.
Here somebody tells that this time is around 15/20 hours, one hour ago I was called by and official repair shop which
told me almost 50, but nothing precise or formal.
I know it's not properly the same but last year I stripped down a cj3 in my garage with few tools and in about 3 days ( 20h),
but unfortunately i'm not and expert, only an enthusiast and obviously this is not enought for an insurance company ;)

Unfortunately chiltons and haynes are pure repair manuals,
with no "timings". These times are present only on
official chrysler/jeep books I think.
Anyway i've some for tjs, cherokees and z/wjs (in pdf - for a swap project i'm going to start on another yj. That will receive 5.2/5.9 or, if i'll find dimensions and weights, a 190kw less thirsty 4.7ho powertech)
For sure in the next order i'll purchase a real paper one. And for sure next shopping will be at Morris in FL, I already bought there many times.
For my problem I think i'll go as Jacobandnickolas said,
for similar cars this kind of swap is stated around 28/34 hours.

In the front end I had a square steel tube 4-3/4 * 1-1/2".4 millimeters thick I made last year, bent and shaped like a warn one with 5mm flange mounts. It was the only part not damaged in the crash ahah

for the train horn. It also will be installed as your advice

i'll keep in touch, i'll post news and thank you very much for your willingness

North east, 70miles away from Venice. 30 from usaf Aviano base

Sorry, I badly explained. I'm not part on the usaf, although I would have liked ;) and I was born here. I'm not american, although I would have liked to be this too :D I live in a town 30 miles away from aviano, my father born four steps away from the airstrip and when I was 3 or 4 I was there with the nose at the sky watchin planes landing from my grandparents house. We had some friends living at the base, some of them officers, other non-military security and so on. Rented our house for Us people coming here at the base. And things like these, but nothing more.
Also here i'm one of the few who has not even any relative in us, only the grandfather of my dad who died in a mining camp is still there

I forgot. If you want still help I would like to buy a jeep sweatshirt from jeepgear (no customer service answers for international orders) :D
.I'm kidding of course, thanks anyway
