Below are the details of my semi DIY rock sliders in case someone else would like to take that route.
U-bolts and nuts - Metal Tech - $103.71
100 Series Land Cruiser/LX470 Replacement Slider Hardware Kit RP-HP-UZJ-22000
The kit came with 4 U-bolts. Had to be buy 2 sets to get needed 6 - have 2 spare now.
Custom 71" slider kit - XO FOB - $370
71" slider kit welded $255 ($195+$60 for welding)
Custom plate kit - $50
Plates 3x 8 9/16 1/4 thickness with two holes with 7 1/8 from center to center.
Gussets 1/4 thick
Discount - $15 - mention IH8MUD
Shipping - $80
Total - $370
Powder Coating - $100
We had to measure the legs, cut properly and weld it. After welding, got it powder coated.
This was some work to be honest but end result is satisfactory.
Initially I was thinking to get bare metal step slider for $650 from BIO but shipping of $250 was a killer.
Total was $370+$104+100 = $574
I ended up buying a welding machine $1K+ which blew the budget out since the older welding machine did not do the justice. However the welding machine could be and will be used for other projects. Of course, I could not do this without my cousin who had done welding for years but years ago.
