I've got the LS2/LS7 TBs, I have 6 cores. I do not have any completely polished inside and out like shown with the polished Maggie above at the present (I can have one of my cores ported and polished on the inside and out in a couple of weeks). I do have several ported and polished inside only. Ported and polished only I can ship pretty quick, like today. I'd have to charge for the core though. I'm not an expert on the conversion from the 5.3 TB to the LS2 unit but I have two cores of the 5.3 TB too. I can open up the outer bowl of the 5.3 pretty good.
wrprice@verizon.net if you want more information. Way I like to work it is you send me a core charge and when you replace the unit with a working TB I will refund it. That way you can hold on to your core a couple of days after installing the new unit just to make sure everything works fine and you won't have any down time. My core charge would only be what I can get them for which is the same as the ebay deal. Sometimes you can get them cheaper but that is hit or miss. Instead of going to all that trouble, paypal, and shipping expense I'll sell you the core for that same amount, $225. Either way, I will work with you.
