In regards to LMC, you are not alone, I stopped buying from them. LMC consistently provides parts of questionable quality.
They also mark up items some items 70%, see below.
Always better to go with Reconditional Original Parts or NOS.
Here is post I made on
The Stovebolt site entitled "Caveat Emptor: Buyer Beware" way back in January of 2007:
Hope you guys learn from my oversights........
I bought a bunch of parts for my '65 Chevy from LMC before Christmas. I competitively checked prices on all of the items before placing the order except for the rear coil springs. The springs were $170.
The springs had a "CPP" Classic Performance Products sticker on them. I looked them up on the internet, the springs were $100.00
A $70 mark-up by LMC? What the ?@#!!
I called them, informed them of the 70% mark-up and asked them what they could do to make it right? The gal snapped back "we don't do price matching!".
I sent the coil springs back to LMC and bought them from CPP.
Even though I had to eat the shipping charges I still recouped some of my losses.
Now I fully understand that this is my bad, I should have checked around. But I still feel that LMC is price gouging on this item. There are a lot of other options for pieces parts; you can bet I won't pick LMC as my first choice in the future.
