Stock peg brackets- RD350 & RD400 interchangeable?

[RDnuTZ]

seems I lost the stock peg bracket for my RD400 project I disassembled 20+ years ago    I'm seeing lots of used brackets on eBay and some say compatible with both RD250/350 + RD400 while others only list 1 or the other compatibility. Are they actually swapable? Yamaha part numbers have similar -27412- so guessing they swap?

I don't think so, the spacing between the mount holes is different. I can verify later today.

Thanks for the offer, but I think I got this  I bought a bracket (no pegs) off eBay that looks really straight and paint in really nice shape and should arrive end of next week. I sold several RD350s before we moved in 2017 and think I put my 400 pegs on 1 of those 350s since the 400 project was on way back burner indefinitely. I remembered yesterday I still have a pair of 350 pegs for a coming build and also my 400 frame is in the shop too- had the ah-ha moment yesterday that I should walk the pegs over to the frame and try fitment myself!    Can always return the  bracket from eBay for refund if I don't want to keep it.
