hello, just tried to put some fiesta zetec alloys on my 1999 escort van to tidy her up (was told they would fit straight on) but noticed the alloy was rubbing on brake caliper, wanted to know what size spacers i would need to keep them looking normal, if that makes sense. old wheels are 6j 108pcd et 35mm upto 38? and zetec are 5.5j 108pcd et 43.5. all answers appreciated.
