Hey 4spd. The only way I can get the top one to fit my 340 is with a torch and a welder . lol
Are the holes in the bottom tray slotted. My phone blurs the picture when I enlarge it. If not a slot is the measurement the same across both trays center to center?

Both trays center to center 9" long. 3 1/2" center to center.

Measurement outside on both was similar. Approx 7/8".

Yeah within 1/16 of each other. Bolt holes are different sizes. Didnt measure those. The older looking ones appear to be 5/16"??

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.
360 tray, 3577 794

318 caps are shorter and require the washers to work.
360 caps are as tall as 340.
