Looks like a great / fun project you've got there,

I don’t own a 8ight so can’t say anything about them.

It does look like you will need to swap out the front left and rear right arm though.. (looks cracked and bent ?)

. I have heard that the 8x & 9x do run hot so just watch your gearing, the medusa sounds like a better application thou
Of course you'll need to completely strip her down, wash and de-sanitize her if you ever hope the get the Nitro smell off it. LOL.LOL.. hours of enjoyment!..
Again looks like a great project, please keep us updated it’s status..
Have a great week and thanks for showing your latest badboy!..
