Hi The merge collecter assembly, T-3 Flage, header flange, as well as one of the primaries were done in Pro-E. Are you looking for native files? if so do you have wildfire 3.0 as Pro files are not backwards compatable. Can you use a STEP file? Let me know and I can e-mail them directly to you. I can only ask that you use them for learning and not selling. All my parts I design are for my personal enjoyment and 1 offs. All my parts I do are done in 3-D on the computer first. Here is a rear strut with a disk conversion for an AP 2 piston caliper (same as a Lotus Esprit Front) using 300zx turbo axle shaft, bearings, parking brake and rotor. I guess thats a different page topic, sorry
