10s in 8T

So I ordered 2 5s 2500 RCM packs from Mike and I was concerned about the dimensions of the packs that he had listed, Mike had listed the packs having a depth of 29mm and the tray had a width of about 53mm I thought I was going to have to do some customizing to the tray. I was able to lay each pack on its side and width wise is a perfect fit they are about 20mm short length wise I think I will use some of the low pressure insulating spray foam for windows it is a softer foam, and they did come complete with a female Deans on each pack( I wasnt expecting that)......
