Stika525...I wish i had a digital camera....I would show you how i modified my 12LW.....the 12L3 chassis is a little different than the LW, but i think it would still work...its basically the same system as the CRC , but it uses a graphite cross brace instead of a rubbber band..i'll try to give you a visual in words......1st. find the thick web that will sit between the cells..drill a hole about (for a 4-40 screw)3/16 of an inch in from the edge of the chassis(dead center on the thick web)you will need 2 skinny body post....(older assoc. style works well)...attach post to new holes(you may have to remove some material from the side of the post where the battery bar will touch)now you will neeed a small piece of graphite or f-glass(approx 3/8" by 5-1/4")(this will be the cross brace)drill holes in the end of the brace,so it will fit over the post......insert cells in chassis,slide brace across cells and over posts...push down brace and mark post for a hole....the hole is for a body clip that will hold the brace......"WALLA"...I have this on my 12LW and it has worked flawlessly...now, all you have to do, is remove 2 body clips pop off the brace and BAM...cells are out....no more tape...hope you get an idea of what i'm talking about....It would be great if Associated would modify the chassis for this...just a little dimple like the 12LW used to have for the body post....Associated...just remember where ya' got the idea from.....K
