How long are they from hingepin to hingepin fronts and rears. Thanks

That helps on the rears but how long are the fronts compared to stock?

like 7/16" longer than a stock wide track arm. hence the reason for using them on a 10t noseplate/bulkhead.

How long are the stock ones? I dont have any to go off of. I have a frankenbuggy coming together and I think I found something but im not sure how long of arms I need.

The stock wide track arms are 2" center to center. I THOUGHT that the RPM Worlds/Kleins were 2 3/8, but SCR8P would be far more authority than I. FWIW I've considered using Ultima front arms on the stock buggy nose plate for fake worlds setup. Ultima arms are 2 1/4 center to center, so they are a little shorter then the RPM worlds/Kleins. I think they'd work with the buggy nose plate, and B4 rims, with stock hub carriers/steering blocks/axles. Alternatively, you could put them on the truck noseplate/bulkhead, but you'd need to gain a little more width back by using wide gt axles w/ stock blocks/carriers or switch to the B4 stuff...

Anybody with a set of worlds arms want to chime in here?

I just measured mine. The stock front arms are 2" kingpin to kingpin center. The world's arms are 2-3/8".

I also have Andy's Ultima arms. They are longer at 2-1/2". They used to be on my JRX2 which had stock arms at 2-7/16". This puts them right between the world's and Ultima arms. I wouldn't use the Ultima arms on an RC10 since they aren't swept back as much. This is a byproduct of front end rake. They need to be swept back more. The JRX2 and Ultima had a 20 degree nose kickup. If you want to use an alternative front arm, use the JRX-Pro SE arms since they are swept back the same as the world's. They won't just bolt onto the RC10 bulkhead though.
