[Fot] TR6 J-Type Gearbox in TR4?

[Steve Myers]

I'm sure this has been discussed many times before but I was always looking for an A-Type not a J-Type.  I know it will require different rear mounts.

Today a guy dropped off a ton of TR6 parts he didn't want anymore and one was a TR6 gearbox with the J-Type overdrive.

I've thought about wanting overdrive in my TR4 racecars to keep the revs down a little more at Road America but is this a good idea?

My car seemed very competitive as it sits now and maybe it isn't worth the trouble, or at least not the gearbox I would want.
