dana 35 ttb same as AMC Model 35 Reverse IFS Front?

[greymarketassets]

I am looking to swap gear ratios on my 1994 Ranger 4x4 front dana 35 to 4.56. I am a little confused by part listings. Yukon gear lists the front diff by application As "AMC Model 35 Reverse IFS Front." Richmond gear lists a dana 35 and dana 35 JL diff but not by application. Any help appreciated.

"The Dana/Spicer Model 35 ... has been manufactured by Dana Holding Corporation since 1985 when American Motors (AMC) sold its axle tooling equipment to Dana."

The critical factor distinguishing TTB gears is "reverse". But it seems like everything is out of stock again. Yukon lists 4.11 and 4.56, both backordered.
