I'd suggest bolting the inner aprons to the cowl, don't tighten any bolts leave them finger tight. You'll see where the fenders bolt to the apron and cowl. Note the radiator support goes in last, and don't forget the "inner" fender braces. Once you have it put togeather start lining up sheet metal and tighten bolts. Do you still have the cowl to fender adjustment rods.
