Can anyone help me? I bought a Lozzi eight RTR truggy from Amazon three months ago. Not sure what version it is. I blew out the front differential and bought the upgrade 8XT but it won’t fit properly in the old housing. It was a complete 8XT built differential, but the mounting brackets don’t lineup with what I have . I would love to use the upgraded differential, but I can’t find the part number for the upgraded housing that will fit by RTR please any help would be great.
