question on turbo spacers for rear and front
 

i had a 77 turbo set up and upgraded to 85 trailing arms and brakes, problem i bought the arms and came with most things but the bolts to mount the tires are small and the bolts are to short to put a spacer on my 77 had longer bolts with 1 inch spacer and room to put the tire on, here is the question are these the wrong bolts does a 85 turbo use both front and rear spacers? if so must i use my front and rear spacers and lug bolts from the 77 or are there a different set for the front and rears thks
