Hello the e40d just went out on my 90 bronco no real surprises their and im wanting to drop a standard conversion into my bronco i do some light trail driving and mudding on the weekends and was considering using the t5 out of a mustang for the better street performance because the truck is my DD but unsure of the cost of a 4x4 conversion on the t5 and the drawback on off roading due to street gear ratios or if i should just drop a np 435 out of an older f250 and bite the bullet on gas millage an info would be much appreciated
