Just thought I would post this for anyone that, like me, is hard up for money but would like to upgrade. This H/E will apparently bolt in stock location and is roughly 30% bigger than ours. I don't know much about the fitment or performance but TVT should be able to answer any questions. Just a thought so good luck.
