These are not that expensive of a part, and I'm not making them, the problem is you have to buy 500 to purchase them.
These block off the heater tube from the exchanger if you have a one hose system.
Wanted to add these to the catalog, for those that need them.
I'm bundling the engine tin grommets and a wiring harness grommet in.
Summary
1- Block off cap $2.99
1- Block off with engine tin grommets (2) $12
1- Block off with engine tin grommets and 1 wiring harness grommet $15
The key here is the block off cap
So, who needs em?
