I hope if you narrow one down you show us how step by step. 

Yes, ofcourse I will share any progress I make in this thread

I did a brief check and the lower arms for DT-02 chassi have the following measurements. Critical is where they attach to the chassi, it is actually about 25,5 mm, the C-hub /wheel side can have whatever inner width fitting a particular C-hub.

And, ideally the arms should be somewhere about 2,0 to 2,5 cm shorter to draw the wheels in under the Holiday Buggy wheel arches / fenders. Then depending on what wheels are used, some are more or less "off set", wheels will be more or less in line or at least much less outside the fenders than they are now.

Actually I think the Holiday Buggy body wasn't meant for the DT-02, the wheelbase isn't correct, notice the rear wheel. Wheelbase of the DT-02 chassi is too long.

There is thread somewhere on TC where one was exploring the different possibilities of alternative arms and hubs for DT03/DT02. It might be of interest in this context, as some of the 4WD chassis have larger gearboxes and have similar fixation anchor points (and that for both front and rear). The guy was not trying to narrow a DT02 but to do something else, but he listed down quite a bunch of alternatives...

(Sorry if if mention the other forum here, but it could facilitate the search and we are quite a few of us posting on both forums)

Thanks. Any info on this is useful. You have a link to the "TC" ?

Tonight I'll take measurments of the dt02 and terra scorcher boomerang thundershot arms. I have all parts here. 🤪

I remember having seen a list in one of the thread I was looking at recently, but I can't find it right now. Not sure where it is but it was on Tamiyaclub...

Unsure for adaptability.
length looks good but other .....

Ok TamiyaClub is TC, ofcourse. Thanks.

And thanks Sting for comparing the two arm-types. Looks like the blue arm is still too long. It needs to be at least 2cm shorter, preferably 2,5 cm to sit well under the fender of Holiday Buggy body.

I'm thinking maybe arms from a G6-01, I do have a Konghead. I'll give it a try, maybe the arms will fit.

I frequently search for Tamiya, Newest on Thingiverse.
One element popped up recently of interest in this thread
Tamiya Holiday Buggy DT-02 Narrowed Rear Arms by FlakJacket - Thingiverse

Maybe worth to look at...

Thanks Silver. Blue and all, perhaps it is these that the japanese guy used in that clip.

I've put my Holiday Buggy on hold for a while in favour of more pressing issues at the moment. But I will return to this as soon as I'm able.
