Works great
Fit like it should and had zero issue used on a LS swap on a 1998 Chevy k1500 with the original 4L60

LS flywheel transmission conversion
Used on a 2001 Chevy lm7 5.3l bolted up to a v6 4l60e. Fit a 1500 v6 torque converter and a s10 v6 converter, one being the larger pattern the other the smaller. Corrected the spacing for a non-LS small block converter up to the LS platform. Slightly noisy when cranking but works. Great price to complete a junkyard swap on a budget. Quality is with in reason for a street vehicle.

Good part
Had an issue with the snout adapter but nothing major.

Wow
Man even shimed the starter sound like an old Chevy truck needing a starter shim or two. No matter how many I've put in it. It maybe the starter.

Watch out!
Stacked parts over the winter just went to install this on my 5.3 and it is warped, and with the ugliest welds Iโve ever seen there is no way this is balanced

Worked great.
Worked great for getting a V6 4l60e mounted to an LS. The bolts it comes with aren't the greatest though. Seem like they would round off easily, just use OEM bolts.

No bolts
Well over priced for a poorly made flex plate... and on top of that... they never included any of the bolts!
