Summit Freeze Plug listing incorrect

[oldcarnut]

I had ordered a new set of freeze plugs along with some other items from Summit. http://www.summitracing.com/search/make/PLYMOUTH/engine-size/7-2L-440/engine-family/Mopar-big-block-RB/Department/Engines-Components/Part-Type/Engine-Block-Expansion-Plugs/?Ns=Rank%7cAsc
They list those 3818002 for the 440 but got them in and they are 1 1/2" and wrong size. Checked Rock Auto and got a part number3818011
Anyway Summit has them too and they will exchange them for me but thought I'd see if others ran into this or at least pass the info along. http://www.summitracing.com/parts/SLP-381-8011/Application/?query=Engine+Size%7c7.2L%2f440
The 2nd number I pulled by part number search as it doesn't come up under the engine search

They also list a MP alternator bracket in aluminum that is steel.

I get most of my stuff from mancini, no issues

I have an oil tube\dipstick for a 340 from Mancini when I ordered a RB and in my notes list a 440. I also got a valley pan with heat riser when I ordered the blocked off style & the invoice shows that. Sure I could have sent the dipstick back but not worth the trouble & I didn't notice the pan was wrong till after I opened it.  In other words Mancini screws up also.
