Midwest Parts
Link above shows a place that already makes the UC MK II engine covers. Looks like the 4-piece upper set will cost you $395 and the lower four individual covers are $72 each.
Sort'a makes Stewart's point that the prices I posted earlier for single items being fabricated isn't really all that bad in comparison. And we can get them a lot lower if other people need the same parts made in a single production run.
On the top engine cover I had mentioned, it is a large piece of flat metal with multiple rows of milled ventilation slots in it. Not louvered.
And we'll be looking into having the recovery cable horns made once I can locate the right kind of channel metal they used in the originals. Thing the flared edges would be hard to make in the raw metal prior to bending but might also be the only way to do them. Its the same metal used for the headlight mount and guard. Know three people that need the horns now.
