Olds. starter adapter question

I been asked if i want to sell a Hildebrandt starter crossover adapter for 49 Olds, also the oil filter adapter plate that goes with it. Can anyone tell me what its worth ?

 

between $150.00 and $225.00 depending on condition and production number. Ive got three of them.

 

You can get up to $300.00 on that crooked auction site e-buy between november and march when people are looking for parts for their projects

 

thanks for the info, the only number on housing is 54-2
