Look else where if i were you, the 236's will come up too short (you won't be able to get the spoke into the nipple) and the 242's will be too long and potentially you will run out of thread on the nipple with the spoke poking thru into the rim.
EDIT - 242's might work on the front but i'd suggest getting 240 front and 238 rear. Have you tried cyclebasket?
