Would this help: or this:

Thank you Diego Baca! That is very helpful information.

This is a needed topic. I hope some solutions are shared here.

61684 is not a part number. I don't mean to confuse everyone but, (from Bricklink) the two currently made 4x4 turntable parts that lock are: "Turntable 4 x 4 x 1 1/3 with Black Square Base, Locking (87081 / 61485)".

When there just isn't a suitable solution using unmodified parts for a build, I do cut parts. For example: I just tried using 22484 bar with towball, which works well if you cut off a couple mm from the end of the bar. Also part 65578 works very well when placed similarly to 79194/25893. Part 65578 must be fully seated to work well and not be too tight/long. 22484 65578

Could someone please share the part number for that domed part. Thank you.

"Also if bits are missing is it acceptable to replace with a new piece (same size and colour of course)". Used sets are definitely worth more if they are complete. For value check prices on Bricklink or https://www.brickeconomy.com/

The normal top for this base is 30658 which has ribs that lock inside the ring and a center snap portion that goes into the hole of the base. What is the part number for this dark tan piece? Look at the underside of both this part and 30658. You will see what is needed.

if these two blue pins are "new" on this step, just locate them where they are gonna be now.

I'm flattered when someone wants to build or modify my work, especially when I have worked so hard at it. I definitely expect to have my work credited to me. Yes, I give credit when I'm inspired by someone else's work, even when it is only a small but unique portion.

You need to talk to Battery Powered Bricks on Youtube. This just one of his many helpful videos:

This set came out like in 2016. I don't think Lego was doing that yet. My Instructions (US) do not have numbered bags, but do have 4 sections. Something else you might want to consideris when building this: https://rebrickable.com/mocs/MOC-5236/Didumos/42056-porsche-911-gt3-rs-unofficial-errata/#details
