Lotus 79 lotus 88

Amigos, im sorry, ive posted this before, and i got great feedback.
Im still making my legendary mod for my personal use, specially in this social isolation moment.
I got cars not converted and apparently i am terrible on understanding how to convert to gp4.
Is someone here willing to send me:
lotus 88 (banned car)
lotus 79 (1978)

modern helmets of:
Jim clark,
Ascari
moss
Fangio

for now thats it. Id be deeply thankful and even willing to pay for the service in case there is any creative work on it.

regards.
Hope everyone is fine!
