I have an 8074 on my disco, but it is basically the same:
The bumper came from eBay, but is made by $corpion racing. Whilst I have a very low opinion of scorpion generally, the bumper I have is pretty good. It is not the one for the 8274 however, and I had to modify it to get it to fit. The winch is also a very tight squeeze in there - there is very little room between the radiator and the back of the winch, and I had to slightly modify the bonnet release mechanism to get clearence at the top. To be fair, using the right bumper in the first place may well mean you don't have to do the modifications I did, but I wanted the winch to to as tucked in and out of the way as possible:
I am running very soft springs, and the front is still pretty high. I don't think standard ones would stand up to the weight of the bumper and the winch though.
Hope that helps
Cheers
Mark
