how to add parts to a truck without blender

[@Primal-Logistics]

This sorta works but sorta doesn’t, tried adding different mirrors to my glider and they aren’t in the right position to fit the truck so seems like blender is always necessary for adding parts

how would I fix missing textures ?

Sorry if this is a stupid question, but will this work with 2 totaly different trucks, like the k100 and the BSA Classic ?
