Nissan Europe cant help me!

[RS13U]

I´m in the process of gathering parts for my 5 lug / 300zx swap on my s13. I have complete front and rear hubs,spindles and 30 mm iron brakes from a 1993 2+2 300zx TT. There are no shops in europe that sell conversion hub for the fronts (that i know of) so i thinking of getting the front hubs from the 05/1995 and newer infiniti j30 (part number 40202-4p000) and the rear hubs and bearings from a 1993 300zx N/A, that i dont have the oem part number. The big problem is the Infiniti brand (and the 300zx N/A) was never sold in Europe so no one recognizes the parts numbers. I have two choices. 1: get all the oem parts numbers for the parts i need and have it ship from the USA or Canada. 2: give the european nissan guys another chance if some one can provide me with the chassi number for both these cars because they tell me that with out the chassi numbers they cant identify the parts. (dont know why but they told they would prefer a canadian chassi number). I have been searching for months,i have even download and study all the service manuals for these models, so please if you can help me out i would realy appreciate. Thank you Niconauts.
