early A body engine swap

With the 273 style Brackets 2710 (Napa 606-1653)biscuits from a diesel '90 W250 are close to the correct thickness and have locking tabs. The hole in the mount for the alignment pin has to be moved a bit.....
2469 aren't thick enough and let the engine sit too low.

With the Shumacher conversion mount the 2469 may be thick enough.

Thanks for the info! I'm genuinely surprised how difficult it is to find information about the mounts. I can't find any official info about the thickness of 2265, my local dealer tells me it's 36mm so that would be hair under 1.5". Rockauto tells me that 2469 would be 1.5" and 2710 would be 1.75" thick, so that makes me second guess the info from my local dealer. I need the replace the mounts with something ASAP just to get the car back on road, so maybe I just order pair of 2265 and try to look into the mounts and brackets with time. I would like to get either solid steel or poly mounts, but the options seem to be very limited. Looks like Moroso steel mounts are only 1" thick so they are probably way too low anyway. Maybe best long term solution would be if I try to source the 340 / 360 brackets and get poly mounts from Dodge polyurethane engine mount

Edit: After some googling I can't find anything which would indicate that there is height difference between 273 and 360 mounts, only difference I could find was with the mounting tabs.
