I moved my 72 x-member to the other set of holes in the frame, hooked the linkage back up, re-did the 72 driveshaft and went for a ride.

Easy and quick

As mentioned above.........if you can figure out how to "search" there is a ton of info on here about this. I never seem to be able to get anywhere but I think you have to type it in "word perfect"

Who knows???

Re: 71 suburban th400 to 700r4 swap

you just just need a lock up kit in your 700r4 for the converter and get a later one if you can out of an early 90s pickup/van. the 700r4 is the same length as a longtail th350, im not sure how youd get an extra spot on your shifter/shift indicater, but you could go with an aftermarket lokar floor shifter.

Re: 71 suburban th400 to 700r4 swap

700r4.com use to sell new shift indicators that had the correct pattern on them. befor eevery one was selling wiring kits for the lock up converter we use to just get a break switch from a newer truck with the extra wire conection and wire it to the trans so that the converter would unlock when you hit the brake. Funny thing is now if you do a search for how to do it you cant find it. 700r4 use to have a tech right up on there site when they were first starting out on how to do it this way but now they sell the kits.
