Hey ERC,
Welcome to the Forum ! It's a great bunch of folks and you'll get a lot of help
and advice. As to your 100-4. Here's what the correct steel fenders and
aluminum shroud would cost you from the UK ( AH Spares) in pounds.
Front fenders - 575 lbs each x 2
rear fenders- 465 lbs each x 2
front shroud - 1845 lbs
That's 3925 pounds and at a recent exchange rate of about $1.55/lb you
are looking at $6084.00 more or less before you pay freight over here which
would probably cost another 20% at least, maybe a lot higher. Then you have to
fit them - a big deal, then paint so you can see you're looking at a lot
of money. Maybe you could find nice used pieces but still have the same issue
of fit and paint to deal with.
However if you're not worried about originality and it looks good to you,
then great. I would just factor in the reduction in value/sales price on
this 100-4 as if you pay what a nice one would bring with the correct sheet
metal, IMHO you will have paid way too much. I'd deduct $10k for the glass
panels off of whatever price he is asking as you'll have that much in it
by the time you're done.
Good luck,
Mike
