That should work, and if you do hit something unyielding, make a wonderful noise!!

The latter part of your comment is true..but the first is not.

I am going to piggyback a bit on this thread..to illustrate the problems here with format.
The joy of automobile forum is that it harnesses many minds to analyze an often common problem, discuss solutions and finally, many people to go out and try them and report. However, the format HERE has been altered by 1-2 individuals. Individuals discuss nothing before and, go out and try a single-mind-in-a-vacuum solutions and present it for sumptuous approval. Those of us amateurs who see its failures are courteous and say nothing and those that don't applaud. In that way, the mistakes curse the community forever.
The earlier Roadsters (which I am a fan of) have a grave problem at the sump. Here is how other forums would have handled it
1. It would have been recognized that the problem has a number of elements.
a. Low clearance. Though other Morgans..Plus 8s until 1996ish and VERY bad until 1991) but steel sumps dent rather than shatter like cast aluminum. As well, the later 3.9 sump leave more ground clearance while ADDING capacity. I keep an extra sumps for all my Plus 8s. When one dents, I swap in the second sump, bang out the dented one with a heavy hammer and a 2x2 and put that one in my stores in waiting.
b. An aluminum sump.
2. That protective plates lower the clearance further
3. That leaving no clearance between a metal protective plate and what its supposed to protect does NOT mitigate the force of an impact to the sump. This can be tested by merely taking the plate before installation, putting on the designer's hand, and whacking the plate with a hammer force sufficient to raise a Roadster off the ground. Now examine the hand and post pictures of it to the forum so we all know what will happen to the sump. Yet leaving more clearance that will REALLY help the sump will also lower the ground clearance where each millimetre is precious!
There is also a possible problem of increased engine bay heat. The two directions that could help here is increasing ground clearance..a la Mulberry or finding a steel sump. If a skid plate is wanted, try something along the lines Alpha Romeo used.
So the solutions given here move this model backwards. It was less likely they could have happened if the format was different here and people wanted to bless this forum rather than use it as an audience.
