all the same stick, just the orientation of the tp-ma board is different and if it comes with shaft cover set and wiring harness.
edit: get this http://www.lizardlick.com/Sanwa-JLF-TP-8YT-SK-Joystick_p_260.html since its the only one in stock. you’ll be using your existing harness in your stick. i’m not to sure if the tp-ma board is at the correct orientation but all you have to do is pop off the square gate and rotate it accordingly.
Which HRAP model is this? If it’s a vanilla HRAP2 or 3, then you’ll need to remove the mounting plate (or get one without it in the first place). SA HRAPs including the newer V3-SA can mount with the mounting plate.
There is a model of HRAP, I think the HRAP EX for 360 that uses this JLF with Microswitch tabs, because the board is non common ground. Sanwa JLF-TM-8T-SK Joystick
