negative Squirrel. Start looking at ATV radiators, specifically hondas. I think I remember someone telling me they got one. for now, DO go to your autoparts store and get another seal, double up on your seals to reseal it. Course, this is only temporary. (as im sure you already know)
OK, here's info someone from the HawkGT site sent: NAPA part #703-2443 or NAPA part # 703-1443 same cap, different pressure settings. I'll check and report back
