Thanks guys. Have a '96 Disco 1 with manual transmission.
The diameter of the input shaft on my R380, where it fits into the pilot bushing (spigot bush) is approximately 0.751 inches.
Purchased a Chevy conversion kit. The pilot bushing I was supplied with has an internal measurement of approximately 0.593 inches.
Discussion with the supplier indicates their kit was for 3.5 and 3.9 engine vehicles. Mine was a 4.0 (looks like Rover switch to 4.0 in 1996 ?). Everything seems to be lining up correctly except for the pilot bushing issue...
The supplier is saying that the manual transmission on the 3.5 and 3.9 Disco 1's have a smaller input shaft diameter.
Purchased the kit over three years ago. Don't recall the web page for the kit indicating the 3.5/3.9 only thing, but I suppose I might have overlooked that...
I'm looking at having to try to remove 0.158 inches from the bushing, but am thinking I might bugger the oil impregnated bronze bushing by closing the surface pores. The other option is to machine the R380 input shaft down to the size of the supplied bushing, but am wondering if this would negatively impact the transmission.
Anyone with some experience or thoughts on this? Find an R380 from a '94 or '95 D1? Replace the input shaft with one from a '94/'95 ?
Are we talking about a brass pilot bushing for the rear of a chevy small block? A vise and a drill bit should be fine.Thanks for everyone's input.
The supplier has basically told me I'm on my own.
I'm starting to look around at custom milling shops, my own metal lathe or finding a long shot off the shelf solution...
