90 Blazer seat mod
 

I have a 90 blazer with worn out really uncomfertable seats. My seatblets in the front also do not lock so they do none any good. I am thinkng of replacing them with newer chevy truck seats like out of a extended cab that have the seat belt built into the seat. What would I need to do to get them to work? Also, if you know any easier way to put better seats in? Thanks
