Im going to try and merge the shorty flap file I got with a scan of the base flaps, part numbers 76621-39395 and 76622-39395, and see if I can make a full length flap file to print!
Also threw and email out to the link in @PlasticsGuy's signature,
DuroBumps Premium Off Road Road Bump Stops to see if they by chance ever ended up making those rubber versions of the flaps.
Even if it was more than $75 id be interested.
Update:
xcmtb83 posted a while back:
It appears Toyota part numbers are as follows:
Driver side: PT413-35966-DF
Passenger: PT413-35966-PF
The manufacturer's part number seems to be different. It appears they are:
LH: 00547-35961-DF
RH: 00547-35961-PF
I used these alternate part/ manufacturer numbers to find a full length flap on a landcruiser parts site used.
Looking forward to scanning this, mirroring it, printing it, and sending it to plasticguy so he has something to make a rubber mold with.
FYI spoke with plasticguy over email and he put the project in hold because he couldn't get a physical flap to make a mold of. I hope to change that!
Update to the update:
I was able to get the passenger side flap in my hand, hope to scan it this weekend and get something mocked up for a Drivers side flap. If anything ill upload the files to thingverse or some repository.
