Different fan shroud or cover

[ddp]

I have swapped my original 350 for a '92 TBI engine in my '71 Cheyenne. The new engine uses a longer water pump and the fan sits closer to the stock 4-row radiator, so my original fan shroud will not fit. I'm not so concerned about a shroud for cooling as much as a cover to prevent someone or something from hitting the fan from the top.

Does any one know of a stock application (6 cyl or different year) with a shallower shroud, or just a cover that mounts to the core support or radiator and extends out over the top of the fan?

Thanks.
