Fan shroud question

[Kenflo]

On a 1973 340 26” radiator the fan shroud part #3673820 seems to be very hard to find. Will the readily available reproduction #2998326 shroud fit? The reproduction is listed as B & E body big block. There are also other 26” reproduction shrouds being made just wondering if any will fit the a body small block?
