I have a 1990 ram 150 two wheel drive with the 5.5" bolt pattern
I want to swap the rear end to an earlier 8 3/4 d100 axle with the 4.5" bolt circle
Is there a front rotor I can use to change the front bolt pattern to match
I already have the truck 8 3/4

yes a 82-84 d series chassis = 84 d150 front rotor or 76 new Yorker rotors = same as truck rotor 82-84
you can also use a set of 72-74 W100-W150 8 3/4 axles with the 5 on 5.5
I used a set of those axle in a 74 C-body 8 3/4 housing on a truck project once already.
are you staying with stock width truck housing? 59" flange to flange?
same as a C-body housing 59" f2f
I have 1 stock 74 8 3/4 housing left with 74 c-body 5 on 4.5 axles.
I just moved perches and installed a 67 C-body (polara) in my 85 stepside. tucked 10" rims in nicely.
what size rim tire combo you going with?
is the rear lowered on the truck?

Scratch. Thanks for the reply. I did some googling and confirmed the rotors that fit.
I didn't know the c body was the same width!
Truck isn't lowered. Planning to stay with the stock width. I may lower it some but I'm not interested in slamming it.
15x10 wheels in the back. Something in the 30/31 inch tall tire that fills the wheel wells
I just got it running and the open 8.25 isn't going to cut it I don't want c clip axles otherwise I'd go 9.25 and a Dana isn't I the budget
I figured 5x4.5 bolt pattern would open up used wheel choices too.
