Default torque converter to flexplate bolts

i'm putting a th350 behind a 5.3l. i bought the flexplate spacer for the t-converter snout for the swap and plan on elongating the flexplate holes slightly so they can be bolted together.

I bought the engine used as well as the transmission and lack the bolts for bolting the converter to the flexplate. Can i use a set of stock th350 bolts or should i use a set off of a 4l60? My main concern is any clearance issues that may result.
Example: any bolts that may protrude out too far and hit the back of the block etc..... hopefully this isn't even an issue, i just want to have what i need on hand before the install. thanks.

How do you install the bolts between the torque convertor and flywheel on the 4l60e since it doesn't have an inspection cover?

Through the hole on the bottom of the bellhousing? Does it normally have a cover or knockout piece or is it left open normally?

Default bolting flywheel to torque converter

I'll probably do mine through the starter access (have to pull the starter obviously). Just rotating the flywheel by turning the front crank pulley bolt since you can't access the flywheel teeth with a flywheel wrench. Much easier if you remove the spark plugs too.

I'm mating a 4l60e to an lq4, but also have to get the bolts. Are they metric or standard?

Thanks in advance!

There is a access location on both sides of the block near the oil pan. Remove the starter on the passenger side and there is usually a black plastic cover above/next to the oil filter for access.

just make sure you buy the correct bolts (SAE or Meteric) that will match up with the T/C.
