What are the best rear seat support trays? Outside of drilling out the rivets and puting in a new base to get rid of the trays.

What are the best rear seat support trays? Outside of drilling out the rivets and putting in a new base.

I saw that the A1 models had thicker support trays. My 86 has some broken pieces on the support trays so I am looking for new ones. I have seen some aftermarket ones from Midwest Military Equipment but someone mentioned they are thin and not like the newer A1 version which are thicker.

Just curious if there is a "best" version out there for the rear seat support trays.

I am looking at #9 in the below schematic. Mine are broken (#19) as well as the lip that locks in the back so looking for new complete units but want to support high back seats.

The seat base you are looking at has the same part number UOC (use on code) for the basic,, A1 and A2 trucks.
Your basic M998 has a UOC of H13, the M998A1 is A13 ETC., you can see all the UOC codes under the parts description
While the early basic trucks may have had thinner plates the replacements should all be the same.

Here is the part numbers for the seat base (support)

A2‘s had the thicker seat base cover due to the addition of bucket seats, they are not necessary to mount different seats, but if you must have them, I have some…but you won’t like the price….LOL

yeah I am finding they are a different part number then the original listed in all the TMs.

It would be simple enough to have a metal shop shear and brake some aluminum or steel in whatever thickness you want it's a pretty simple piece.

Tlambert has already made the drawings.

HMMWV - Rear Seat Supports (12339047 / 12446966 / 12446967)

I am in the process of upgrading to bucket seats. The older style 12339047 have two retention plates to secure the Support to the vehicle. However these will cause issue when moving to the new seats because of the bolt pattern. I believe the seats will be part of kit 57k3196 or 57K3197 (TM...

If I saw correctly, the original is made of thicker material and does not include the braces.

correct. The newer style are much thicker, dont have the braces (the seat is self supporting I guess) and the clamp in the back is a single piece moved to the middle to account for the seat bolts.
