R3 48 9.6Deck Roller

1174X1-16 Chrysler 318-340-360 Ultra Pro Pushrod Oiling

I have a ser of this company's lifters in my ritter block only ones that fit. But I removed the extra bolt holes valley side. Can ask them if they will work for yours. Thought I hot the higher end ones but got the little cheaper ones.
I thought the R3 needed a longer lifter so the link bars would clear the block
The block is getting bushed.
Never used Solids before so it is a new learning curve.
