Small Block Windage Trays Exist in Different Profiles?

FWIW. The MP/DC windage tray that I bought around 1989 has slotted holes and the curve for dipstick. So far I haven't found the p/n.

The Engine Book says this:
340 windage tray, 2531 945 standard Chrysler p/n
install on any LA with:
340 Main cap screws (qty 4) 6027 355 (clearly a later, superceding p/n)
Hemi main bolt washers (2 per bolt) 2468 135
Windage tray attaching screws & washers 6023 092

OR buy the following MP installation package with everything included:
P3690939

Install the 360 windage tray on any 360 using the same installation package.
