difference in trim on 123GT

[red122]

Im in the enviable position of having two cars Im restoring at the same time and as one is a genuine 123Gt i don't want to be putting the wrong bits back on either car from my boxes of parts !!

Are the original seat belts and interior door handles the same or are there any small detail differences I should be aware of before i put them back together ?The other car is a 67 b18 121 which I'm building as a rally car so its generally getting any parts that aren't quite as good trimwise but will be ok for rallying .
The Gt I want to keep as original as possible . i know about the seats /dashtop /steering wheel difference but wondered if any one knows any small detail differences i should be aware of .

Thank you in advance !

Just the recliners on the seats, dash top, rev counter and steering wheel OD column surround with stalk on the inside and badges on the outside
