I came across these RPM front arms and have not seen any like these before. Did RPM make arms that would be a replacement for the Andys pro race arms? They do not fit a 10T bulkhead but are the same length as the worlds arms and the pro race arms. They do fit the Andys pro race front bulkhead. Here is some pics showing the rpm arms in question compared to a pro race, standard andys, stock AE and a rpm worlds arms.

They are truck arms, for monster truck conversion. They made rears as well.

Ok thanks! So it seems they could also be used to replace the pro race arms being they are the same length? The only difference I see is the shock mount holes being off by like !/4" or less.
Edit: Actually the rpm arm is about an 1/8 shorter than the pro race but still thinking I could use them on a S&K chassis with a pro race front bulkhead.

The RPM arms would be short on a Pro-Race front end but maybe you could use GT axles to bring the width back out.
Option #2 is B2 Carpet arms...which are longer than Andy's Pro-Race arms but should work with B4 wheels. Problem with those is the shock mount holes are further out.
Then there's JG Truck arms....which I'm dragging my feet on but will eventually get reproduced. They are as long as the B2 carpet arms but have the shock holes further in. I don't know how well they'd work with B4 wheels though. Might have some rubbing issues like the RPM truck arms.
