You are talking about headlight buckets, fenders & hood, Right, Because the rack will not fit on early Z. The other body parts should work OK.
I would get a Victoria British catalog... The drawing are great, They tell you what years parts fit and the req'd number needed to do the job unlike MSA that just give you a part Num and you got to ask how many do I need... Plus they show like 70-73 Interior and 74-78 Interior drawings MSA shows one then list part by year... MSA can make you go crazy trying to find parts IMO... I use VB to decide what I want and how many to get then I cross over to MSA for pricing and to get 10% off OEM parts....
http://www.victoriabritish.com you can order one on-line and they keep sending new ones all the time. MSA sent one to me 3 year ago and still has not sent me a new copy...
