engine and box can be fitted into the 1200...but really better getting an L18 or L20b and 5 speed box if the stanza one is a 4 speed

what year is your ute, if its later than 76 then it will have all the stanza arms and stuff in the front of it already. if that is the cas you just need to use the stanza balljoints, steering arms, outer tierod ends and tie rods then you will be able to bolt the stanza struts in

if its an early ute, then you use the stanza lower control arms also, and you will need to buy late ute or late 120y castor rods

you can cut the stanza struts down to get a decent amount of travel, cutting them down to suit a 240z insert gives decent travel

you can cut the stanza engine mounts off the crossmember and mod them to suit the 1200 crossmember to fit the L series

can use stanza clutch stuff, but your better off using toyota stuff under the dash
