My 4-speed conversion
« on: October 07, 2006 - 06:57:46 PM »
All in all a pretty easy job. Had as little trouble getting the old pedal assembly out - had to pry out on the bottom of the dash. Forgot to put the spring in so I had to stretch it out and wedge a screwdriver in it, install it and pull the screwdriver out. I marked the out line by drilling holes and used a saws all. It was much easier and less messy than grinding. The tunnel didn't seem to be contoured correctly but I will make it work. It could be because the driver side floor pan had been replaced (pop riveted).  I probably cut the hole to big but it shouldn't really matter. The pivot bracket that goes on the frame has a little tang that fits in a slot already existing in the frame. Piece of cake. Here are a few pictures. Anyone wanting to do this should have no problem as I have minimal skills and found it easy.

I know a guy that put RTV on it and sheetmetal screwed it in   :misbehaving:

(no, not me)
A job like this should be welded in for strength if nothing else.  That new hump in the pic looks sweet!!!

From what I've read, the factory just spot welded them in and slathered on the sealer.  I suppose you mount them however you want.  If you have frame connectors I doubt the support is that important.  I'm gonna screw mine (for some reason that doesn't sound right) until I learn to weld or get it welded by someone else.

You make it look to easy!  Now my mind is wandering to the other side!(4spd vs auto) for all you potty minded people!

No it wasn't a kit.  I just talked to Brewers Performance and told them what I had and what I wanted to do.  I actually had to tke my trans there to get the case changed from B-body to E-body.  I almost kept my car automatic because I had doubts but it is an unbelievably easy conversion and I love banging gears and dumping the clutch.

I haven't installed it yet but I had it installed in a barracuda that was concerted by my friend with the B-body shifter.  It already had the pedals in it.  The service manual gives a very detailed picture.  The conversion is only the pedals, the floor and the bracket that welds on the frame.  Everything else is standard 4-speed.  Bellhousing, linkage, Z-bar.  Oh ya.  I almost forgot.  The crank needs to have a hole in the end to accept the tranny shaft.  If your crank is an original automatic crank it may not be drilled.

That frame mount is what I'd be looking for.  When you do it take some pics if you remember.  My 340 has a bushing in there is that what you mean or is it something different?

The first picture shows the part I got from Brewers.  It is the same as the factory supplied.  Notice the little tang at the bottom right (this would be the view looking through the wheel well from the outside).  There is a little slot on top of the frame located at the back of where the cable tie is in the second picture.  The tang sits in there.  See how flat it sits in the third picture.  This is just inside the driver side wheel well.  It literally fits like a piece in a jigsaw puzzle and will not swivel.  All it needs now is to be tack welded in.
Wa La.... 4-speed.

Way to easy!  I guess I'd have to piece together a kit as the kit from brewers is pretty expensive. :puke:
