Panzer IV and Jagdpanzer IVL/70 - length of hull?

Hi, new guy here and my first question; I have tried the search feature and can't find any relevant info, but that
doesn't mean I didn't miss it.

I recently became interested in the myriad types of German tanks and armor from the '30s and 40's.
I've picked up a few 1/35 models of several types, and that is what lead to this question.

After searching on line, I believe I've found that the length of the hull of the Jagdpanzer IV L/70 is about 3 feet
longer than that of the Panzer IV. Ok, but If correct, where is the difference?

I can see the sloped armor at the front projects somewhat, maybe a foot?
But where is the "rest"?
Is the entire hull slightly stretched?

Or am I entirely wrong in my observation/findings ?

Thanks for any answer or direct me to a thread or other source.

Thanks in advance.

 

Hilary Doyle book comes to mind.

 

My bad. Walter Spielburger's along w/Hilary Doyle and Thomas Jentz's book, Light Jagdpanzers discusses it on page. 138. "WaPruf. 6 suggested on May 16, 1944, that the whole suspension be lengthened 100 mm. to the front which would change the center of gravity for the better. But this change required a. new design for the bow. The front road wheel mounts were already quite close to the drive wheel. Any further extension foward would inevitably led to a collision of the two running-gear components, which would have caused the destruction of the first road wheel by tthe drive wheel." Instead of having rubber, the front road wheels (2 on each side) were steel road wheels and lighter tracks were introduced.

Spielburger's series of books are, IMO, top notch and are the equivalent of Hunnicutt's series of books on American armor.

 

That is the internet for you.

Jentz & Doyle's "Panzer Tracts #9 - Jagdpanzer - Jagdpanzer 38 to Jagdtiger"

Gives the hull length of the Jagdpanzer IV/L70 (V) as 5.90 meters. The hull length of the Jagdpanzer IV/L70 (A) is 5.92 meters.

Some sites have stated the hull length as 6.85 meters...Which is the overall length of the Jagdpanzer IV/L48.

 

Thanks guys, if "lengths" were always noted as to hull or overall(with gun to front) it would be clearer.

The post "tank data books" was especially helpful.
