dB drive plt wd 15" basket bolt pattern/ what will fit?

I've got a 12" db drive wd that i want to recone into a 15. I'm getting the recone from db drive but unfortunately they no longer have the baskets/frames for sale. Anyone know of a similar basket that will fit both the motor and the recone? I don't know the spider landing on the oe basket or recone unfortunately since tech support is closed until monday. Or if anyone has a 15" basket from a wd or t3 tss they would like to sell let me know.
Thank you!
