i bought one of those kits do it to mine, i returned it because it didn't really fit the 4x4 with a trailer receiver. but those kits are nothing special. i think you could easliy use a blazer tank, just bend and make you own tank straps. when i got mytakn from LMC it didn't even come with instructions. when i returned it i got a brand new in the cab tank with sending unit for 1/2 the price.
