Expired Alternator Tensioner Question

Hello Sir:

The alternator tensioner 857441 is no longer available and I couldn't find anyone who had one in stock.

However, I do have the earlier version of the tensioner which should work, but it is more expensive.
If you ordered this and it would not fit we would take it back for a full part refund.

Please let me know if you want to try the 855390 version and I am sorry I could not find the later version.

J.D.
