The front subframes are different, the steering rack mounts are offset. Plenty of front subframes for sale on Ebay UK. I used the pedal assembly, steering column and lighting part of the wiring harness from a UK donor but I think the LHD parts would all fit. Have you ordered the kit?
I have read your build thread many times and am inspired by it. Thanks Snowbird. I will contact Exomotive and order the BRG Replicar kit this month. Just looked at the UK eBay site. You are right. Plenty of subframes! Maybe Exomotive will source them for me. Could I contact you offline if I get stuck? Thanks.
